Cleaning the throttle body is a simple operation for stable engine performance. Cleaning the throttle valve

The throttle valve regulates the flow of air into the engine intake manifold in accordance with the force applied to the gas pedal. For normal operation of the engine, a strictly defined volume of air and fuel is required in each specific mode and at a given speed. A lean or enriched mixture leads to increased fuel consumption, unstable engine operation, and difficulties starting the engine. Incorrect air supply can be caused by malfunctions of the intake manifold and the duct as a whole, but component contamination is more common. Therefore, it is necessary first of all to check and clean the engine throttle valve.

Why clean

The air mixture supplied to the intake tract of a car engine is needed for efficient combustion of fuel in the chamber. If there is not enough air or its volume does not correspond to that required for a given engine operating mode, then the fuel-air mixture will be burned less efficiently. This leads to unstable engine operation, a drop in power, and an increase in fuel consumption.

Prolonged operation of the machine with a contaminated damper can also lead to damage to engine parts.

The elements of the cylinder-piston group of the combustion chamber are designed to work with a certain volume and composition of the fuel-air mixture.

What causes pollution?

Among the main causes of pollution are the following:

• Operating a vehicle using low-quality fuel. Low quality gasoline with a large amount of sediment and impurities is one of the reasons for the formation of contaminants in the throttle assembly.
• Dirt entering through the air supply system. Dust and dirt settling on the parts of the throttle assembly enter the intake tract through a dirty air filter or an air duct with a broken seal. It is recommended to change the air filter in accordance with the manufacturer's regulations (maintenance).
• Fuel filter is dirty. A fuel filter, unlike an oil or air filter, needs to be replaced much less frequently, but this does not mean that it is less dirty and does not pose a threat to engine parts. Dirt from it can also get onto the damper.

Precipitation in the form of oil dust from crankcase gases is also dangerous. Oil with dirt and dust on the valve is formed due to crankcase gases, which usually enter through the valve cover.

Main signs of pollution

The following signs indicate the need for cleaning:

• Difficulty starting the engine.
• Unstable engine operation (engine stalls while driving).
• Uneven engine idle speed (speed “floats” at idle).
• “Stuck” or drop in speed.

How to clean

Every specialist in a specialized car service knows how to properly clean the throttle valve, but not every car owner. But it is recommended to perform this procedure at least 30-50 thousand kilometers - depending on the quality of the fuel used, the condition of the filters and systems.

You can clean the throttle valve without removing the valve or by removing the part. In the first case, an intake valve cleaner is used. First, the air duct is dismantled, after which, with the damper closed, the product, which is usually released in the form of an aerosol, is applied to the surface of the part. Dirt and oil accumulations are removed with a soft cloth. Next, you need to open the damper (press the gas pedal all the way) and remove dirt from the side surfaces and channels. The procedure is performed several times.

Please note that partial cleaning, as well as washing the injectors without removing them, will not completely remove all contaminants from the part. Therefore, it is better to carry out the procedure with removing the throttle.

Complete cleaning

Complete cleaning of dirt and carbon deposits is only possible when the device is removed. The correct way to dismantle the unit is as follows:

1. Disconnect the air duct.
2. Remove the damper by unscrewing the bolts and disconnecting the connectors.
3. Using a carburetor cleaner or a special compound for throttle valves, use a soft cloth to thoroughly wipe the part inside and out.
4. Repeat the cleaning procedure several times, avoiding strong mechanical impact, which can lead to removal of the protective coating of the metal, damage to the damper itself and its position sensor.
5. After cleaning the throttle, reassemble the entire air supply system assembly in the reverse order.
6. “Train” the damper after installation by setting the idle speed to the required (factory) value.

How to clean the throttle position sensor

Contamination can also get onto the position sensor. Due to sensor malfunction, loss or poor contact, the information received by the vehicle's ECU about the position of the part will be incorrect. As a result, the engine will not gain speed - or, more dangerously, the throttle will open completely while driving, which will lead to an increase in speed instead of braking.

Use a liquid and a soft cloth to remove dirt and oil deposits from the sensor without using excessive force.

How much does cleaning cost at a car service center?

When cleaning yourself, the costs depend only on the cost of the selected liquid. As a rule, this amount is around 100-500 rubles, depending on the manufacturer and store.

The technician will tell you how much it costs to clean the throttle valve at a service center after preliminary diagnostics. Remember that the appearance of signs of contamination does not mean that only cleaning is required - there may be malfunctions of the air and fuel supply unit. Therefore, it is impossible to give an exact price without checking.

You can clean the car engine damper yourself, but if you do not have special skills, it is definitely better to contact the experts at a specialized car service center. In this case, you will definitely save time and will not be afraid of damage to the elements of the injection system, which you can cause by unqualified actions.

The task of the throttle valve (hereinafter referred to as DZ) is to regulate the amount of air supplied to the intake manifold. Its position is adjusted in accordance with the position of the accelerator pedal. The damper drive can be mechanical (using a cable) or electronic (using an electric motor). The position of the remote control is recorded by a special sensor. It transmits the relevant information to, and it, in turn, makes a decision on the amount of fuel supplied and changing the engine operating mode. You can read more details and functions in additional material on our website.

Signs of a dirty throttle valve

In order not to confuse the symptoms indicating excessive carbon deposits on the valve, it is better to first visually inspect it, and if there are no visible oil or coked deposits on the walls of the throttle assembly, then, with a high degree of probability, cleaning the throttle valve will not eliminate the problem.

Sami the signs look like this:

• problematic engine starting;
• uneven engine operation;
• floating speed at idle;
• freezing engine speed;
• drops in speed until a complete stop.

Mistakes when cleaning the throttle valve

Many inexperienced car owners can incorrectly clean the throttle assembly, at a minimum risking not getting the desired effect, and at maximum - completely damaging and disabling the throttle body. Therefore, it is important to understand when to do the procedure, how to do it and what means to use.

Dirty throttle valve

Clean throttle

To properly clean the throttle body NOT WORTH IT:

1. Clean the damper in any unclear situation (there are even jokes about this).
2. Clean the damper without removing it (the effectiveness of such cleaning is insignificant, since often it is only possible to remove carbon deposits on the damper itself, and the internal walls and air channels of the damper are not cleaned).
3. When cleaning with a rag, use excessive force, which can lead to damage to the damper itself and to the one located nearby.
4. Use brushes rather than soft materials. This error also quite often leads to loss of performance of the remote control, since on some throttle units the inner wall and flap are coated with molybdenum for even smoother air flow. This layer is often confused with plaque and is removed. As a result, the damper begins to either “bite” or allow excess air to pass through (the speed increases).
5. Forgetting to teach the throttle after cleaning. Dampers with an electronic gas pedal require proper learning of the remote control in order to set the idle speed to the required value.

Cleaning the throttle valve on Mitsubishi and Nissan requires a special approach. You need to act carefully and carefully so as not to remove the protective coating, the so-called “patch” - the sealing coating along the contour of the remote protection. And also mandatory for setting new engine operating parameters).

Throttle valve worth cleaning every 30-50 thousand km. Adhering to all the above recommendations and taking into account the main mistakes that inexperienced car owners make, no more questions should arise about how to clean the throttle valve, be it mechanical or. For cleaning you need a minimum of equipment and costs, just a carb cleaner and clean rags, as well as a screwdriver for dismantling the unit.

Cleaning algorithm

Now let's give a step-by-step proper cleaning algorithm throttle valve.

1. First of all, you need to get to the damper itself. The design is different in different engines. But as a rule, to do this you need to remove the air duct that runs from the damper to the air filter.
2. Dismantle the damper. To do this, unscrew several mounting bolts (2-4 pieces), and also disconnect the necessary connectors (for example, the connector from the absorber purge valve).
3. To clean, you must use a carburetor cleaner. There is a wide variety of them, and in auto stores you can easily find a product in accordance with your preferences and capabilities (we will talk about them later).
4. Using a rag and the mentioned product, you must thoroughly wipe the damper outside and inside.
5. You also need to clean the protective grille (if your car has one).
6. Assembly of the unit is carried out in the reverse order.

Remember that you need to clean the damper thoroughly so that the metal is as light as possible. This will ensure, after its installation, an increase in the dynamic characteristics of the machine.

An easy way to clean your throttle body

The correct way to clean the throttle body

Cleaning without removal

Also, many car owners are interested in the question of how to clean the throttle valve without removing it. Such methods do exist, but you must immediately understand that high-quality cleaning is only possible by dismantling the damper.

To do this, you will need a special product - an intake tract cleaner. You can use different brands. You can also use cleaning liquid, WD-40, and solvents for cleaning.

So, procedure without removing the unit:

1. As in the previous algorithm, you need to remove the air duct to get to the damper.
2. With the damper closed, spray the surface with cleaning liquid and remove the cleaned dirt using a rag.
3. Open the damper and remove dirt from the side surface.
4. Make sure that the cleaning agent gets into all channels. The cleaning procedure is similar using a rag.

Let us repeat once again that for proper cleaning, the throttle valve must be removed from the car. And when installing it back, it is advisable to replace the damper gasket with a new one. Fortunately, its price is low.

As the manufacturers of such products say, they need to be used every 7...10 thousand kilometers. The damper must be cleaned and dismantled every 30...50 thousand kilometers.

It should also be remembered that in most cases, after cleaning the throttle body it is necessary to carry out actions to “train” it. This procedure is carried out either using a computer (by connecting it to the car's ECU), or by manipulating the ignition and gas pedal. In this case, it is impossible to give universal recommendations, since they can differ significantly for each manufacturer and even model. Remember this!

Causes of pollution and how to deal with them

There are several reasons why the throttle body becomes dirty over time. By avoiding their appearance, you will automatically extend the time between cleaning it. Reasons mentioned include:

• Using low-quality gasoline. If there is sediment in it, it will definitely get into the throttle assembly, where it will turn into carbon deposits. Therefore, try to fill in high-quality gasoline and refuel at proven gas stations.
• Clogged fuel filter. If you do not change the fuel filter in time, then there is a possibility that pieces of dirt from it will get into the fuel system, including the throttle assembly.
• Dust and dirt entering the intake system. This can be caused by various reasons - clogged air filter, damage to the integrity of the air duct, various mechanical stress.
• Crankcase gases with oil dust. They are the main cause of oil deposits on the valve. They can enter the combustion chamber through the valve cover from. The situation is aggravated by the fact that they carry oil dust. It is this that burns and remains as sediment on the surface of the throttle valve.

Clogged fuel filter

Change the air and fuel filters on time, fill with high-quality gasoline, and prevent dust from getting into the car's fresh air ventilation system. All this will save you from the need to clean the throttle valve ahead of schedule.

How to clean the throttle valve

There are a number of special products designed to clean the surface of the throttle valve. Some craftsmen use WD-40, acetone, solvents and other similar compounds for this. In principle, they can be used, but the risk of damaging something inside the engine increases. Today, car dealerships sell a large number of special products for carrying out this procedure. All of them are relatively inexpensive. Therefore, taking into account the fact that the throttle valve does not need to be cleaned so often, any car owner is able to purchase such a product.

The cost is indicated as of prices for the summer of 2017 for Moscow and the region

Results

If the symptoms described above appear, check the condition of the throttle valve. Cleaning it is not very difficult. However, if you clean it, the dynamic characteristics of the car will improve significantly. Therefore, do not forget to regularly clean the damper every 30...50 thousand kilometers. As for cleaning products, use any of the ones listed above. Fortunately, they are inexpensive, so they are available to any car enthusiast.

During the operation of a car, various problems arise with the engine, but as long as the engine is in good working order, car owners try not to touch the car, for fear of disrupting the stable operation of the power unit.

However, there are some nodes that require periodic preventive maintenance. Cleaning the throttle valve must be done regularly; if this is not done, the internal combustion engine will begin to malfunction after a certain time and operate in violation of the normal operating mode. Why the throttle assembly is cleaned and what it gives will be discussed in this article.

Types of throttle valves of a modern car

The throttle valve (DZ) is an element of the internal combustion engine intake system; it regulates the supply of the air-fuel mixture or air into the intake manifold. Depending on the type of power unit, there are different types of throttle valves - with a mechanical or electronic drive; on a carburetor engine, the damper is an integral part of the carburetor.

The damper itself is usually attached to the axle with two screws; when it opens, the engine speed increases. Maximum speed is reached when the throttle is fully opened, but the throttle valve never closes tightly - if you close the throttle completely, the engine will stall, since the supply of fuel and air to the intake tract will stop.

In engines with distributed injection, the throttle regulates the air supply to create the required proportion of the fuel mixture; in carburetor engines, a dosed mixture is supplied to the valve from the carburetor. In mechanically driven systems, the throttle is turned by pressing the gas pedal, to which a cable is connected. In electronic throttle units, there is no mechanical connection between the axle drive and the damper itself; the rotation of the damper is “commanded” by an electrical signal supplied to the unit.

How often should you clean the throttle body?

There are no clear recommendations on how often to clean the throttle assembly; many car owners turn to a car service center only when any problems arise with the engine. There is an opinion that the throttle should be cleaned of soot and slag after 40-50 thousand kilometers, while others believe that cleaning the parts is necessary after 30-40 thousand kilometers.

The throttle body becomes clogged with black soot due to low quality fuel, and oily deposits can also form on the throttle body. If the valve becomes coked with soot and oily impurities, this means that there are problems with the piston group or the crankcase ventilation is clogged.

If the throttle body is clogged with slag, the motor begins to operate unstably; the main signs of a clogged throttle assembly are:

• ICE idle speed floats;
• the engine does not immediately respond to pressing the gas pedal;
• The car drives jerkily and changes speed on its own.

If the throttle axis is covered with tarry deposits, it begins to jam, and then the accelerator pedal is pressed with force. To accurately determine the cause of the clogged throttle body, it is necessary to remove and disassemble the unit; the degree of throttle contamination is determined by external inspection.

How to clean the throttle body

Many car services clean throttle assemblies; there are car repair shops that specialize in certain brands of cars (Ford, Mercedes, Audi, Volkswagen, etc.). If desired, the car owner can clean the throttle valve himself - in general, the procedure is not too complicated and does not require much experience or special knowledge.

The cost of cleaning at service stations may vary, it depends on:

• on the complexity of the work (on some car models it is difficult to get close to the remote control, you have to remove a lot of parts);
• level of car service (at a large service station, servicing a car is always more expensive);
• region (in large cities they charge more money for work than in regional centers).

For example, in St. Petersburg, cleaning the throttle at a mid-level car service center will cost from 1,500 rubles; the service costs approximately the same in the capital region. Diagnostics of the throttle control costs approximately 600-800 rubles; car services also carry out throttle adaptation. Adaptation (learning) is performed so that the electronics “remembers” in what position the damper is open and closed. This procedure is carried out in the following cases:

• when replacing or cleaning the throttle;
• after the battery is completely discharged;
• after changing the electronic accelerator pedal.

In order to clean the throttle assembly, parts must be removed; some perform cleaning without removing the throttle, with partial disassembly. But incomplete disassembly in many cases does not solve the problem, since when performing work the DS axis must also be cleaned, and this is almost impossible to do on site.

In order to clean the throttle valve with your own hands, you will need the following:

• car instrument;
• a special cleaning agent, most often carburetor cleaner is used;
• soft rags.

Let's look at how you can clean an electronically controlled ignition sensor on a Nissan car. We carry out the work in the following order:

• open the hood, just in case, pull off the terminal from the battery;
• unscrew the clamps of the air filter pipe;
• disconnect the plugs from the throttle assembly, the outlet hose of the ventilation system;
• dismantle the air filter receiver assembly with the pipe;
• Using a 5 mm hexagon, unscrew the 4 fasteners of the throttle valve;
• remove the throttle as carefully as possible, trying not to damage the gasket;
• all dirt and soot from the throttle must be cleaned off;
• take the carburetor cleaner Carbcleaner, put a tube on the bottle, and spray the composition onto the surface of the damper;
• if there is little dirt, it itself begins to corrode under the influence of the jet;
• We try to apply the cleaner composition alternately on one and the other side of the device;
• wait until the Carb Cleaner is absorbed into the soot and the liquid dries;
• after drying, repeat the procedure, wipe the damper with a rag;
• Also, don’t forget to wipe the insides of the intake manifold in the place where the manifold connects to the DZ. If there is only a little soot on the metal, it is not necessary to spray it from a can; just moisten a cloth with the cleaner and wipe the surface;
• Having thoroughly cleaned the soot, we put the part in place and connect the air pipe.

We start the engine, but if high speeds appear after cleaning the throttle valve, throttle adaptation is necessary. We “train” the damper as follows:

You must act strictly according to the stopwatch - if you make a mistake by a few seconds, adaptation may not work. If the internal combustion engine does not stall at the last start, the entire adaptation should take from one and a half to two minutes.

If the speed still does not return to normal after training, you can try not waiting 3 seconds after the warning light comes on - immediately remove your foot from the pedal and start the engine.

The damper does not need training in all cases; if there is little soot in it, adaptation may not be necessary. Car owners should also know that training should be performed with a charged battery in the car.

Just 15-20 years ago there were few compositions for cleaning throttle bodies in stores, and many car enthusiasts cleaned carburetors and injectors with various improvised means. Now there is no need for this - there is a wide range of auto chemicals on sale.

It’s not worth saving on a cleaner - you won’t be able to save a lot of money, and you may not achieve the desired result. Among the most well-known manufacturers of chemicals for throttle valves and carburetors are the following companies:

• Hi-Gear;
• Liqui Moly;
• 3ton;
• Yamalube;
• STEP UP;
• Abro.

Using cleaners, you can not only clean the throttle, but also the PCV ventilation valve (crankcase gases). Hi-Gear (“Synthetic Formula”) does not contain substances that destroy parts of the fuel system, so the product will not cause any harm. High Gear carburetor cleaner is available in cans with a capacity of 354 and 510 g; a large bottle is usually enough for two or three cleanings. The only serious drawback of Hi-Gear products is the rather high price.

STEP UP carburetor cleaner is cheaper, but in quality it is almost in no way inferior to High Gear. The cleaner comes with a regular and improved (synthetic) formula; the product has a very mild odor.

" you will learn, how to clean the valve, throttle body with your own hands, naturally. The work is not dusty and does not require special skills and knowledge. Moreover, we already talked about this on our website, last time.

It’s worth noting right away that there are no fundamental differences in performing this work on different VAZ models, the principle is the same - remove the throttle assembly, take a special liquid and spray it on the valve. In rare cases, you have to make more effort and rub the throttle with cotton swabs or even a toothbrush.

As always, before we begin, a few words about what a throttle valve is, why it gets dirty and how to understand what is needed cleaning the throttle valve. Go...

What is a throttle valve?

Throttle valve (DZ) is an integral part of the fuel system of a gasoline engine. The main task of the DZ is the dosage of air supply, which enters the cylinders to form a combustible mixture. The throttle body is located after the air filter and before the intake manifold. Simply put, the DZ is an air valve that regulates the air supply. When the throttle valve opens, excess pressure in the intake system disappears; when it closes, negative pressure forms in the system. Every time you press the gas pedal, the throttle opens or closes, since the throttle valve is connected to the throttle cable.

When is it necessary to clean the throttle valve?

Signs of a dirty throttle body and the need to clean the throttle body:

• Poor engine starting, ;
• Jerking while driving at low and medium speeds.

Causes of throttle valve contamination:

• Air. Although it is filtered, it still contains dust.
• Oiling and crankcase gases. These two substances form an oily coating on the throttle body, preventing the normal operation of the throttle assembly. The damper begins to open and close poorly (poor response to the gas pedal).

How to flush the throttle valve of a VAZ 2114-2115

There are two types of cleaning - with and without removal. First way provides for the following points:

1. Disconnect the air filter bellows, remove the pipes, as well as the adsorber pipe. The coolant pipes must be bolted or bent and clamped to prevent coolant from spilling out.

3. After the throttle is removed, it is necessary to remove the sensors ( , ) and clean them.

4. Next, using WD-40 or a special liquid for cleaning the carburetor (for example ABRO), we clean the rear brake. This is done simply, you need to apply the composition to the valve, as well as the inner surface of the throttle and let the special tool do its job. After a few minutes everything will be clean, but if the result does not satisfy you, clean again, using cotton swabs or a toothbrush.

Attention! Never use sharp metal objects!

5. Let the remote control dry, after which everything is assembled in the reverse order.

Second way provides for disconnecting the air corrugation and cleaning the throttle valve right on the spot. The principle is the same: the solution is sprayed on one side and the other of the remote control (to do this, you can turn the damper by hand at the place where the cable is attached). I have not tried the second method, because in my opinion, it does not make it possible to fully clean the throttle valve, so I cannot advise this method or talk about the results of such cleaning.

When flushing the throttle valve, I recommend replacing the throttle valve gasket. Basically everything. You can finish the article about how to clean the throttle valve of a VAZ 2114. I think the knowledge gained will be enough for you to repeat all the steps described above yourself.

Cleaning some car systems is a mandatory task for the modern car owner. The fact is that Russian operating conditions do not spare certain components of the vehicle. Poor quality of gasoline, not very careful operation, dubious origin of materials for maintenance - all this imposes certain difficulties on the operation of the machine. The fuel supply system suffers especially, as it takes on the blow of all factors at once, including harsh climate. Cars have a hard time in Russia, and we have to agree with this. But there are a number of ways to protect your car from problems or return it to its original working condition.

The first thing a car owner needs to remember is the quality of service. Buy original oil, which can cost several times more than universal oil. This way you will protect the engine from many unpleasant influences. It is also worth using good gasoline, which is often not the cheapest. If problems have already arisen, you need to start cleaning the car, and then draw conclusions about proper maintenance and operation. The most common problem in Russian cars is a clogged throttle valve. Let's consider the features of this trouble.

What benefits does cleaning the throttle valve in your car provide?

Cleaning any component of the machine allows you to return to high-quality operation of the equipment. This is why oil and fuel filters are replaced, small systems and important components of your car are cleaned during the service process. But the standard maintenance procedure does not include flushing the throttle body. The problem of clogging this element can occur on any car, because every internal combustion engine uses this unit to distribute fuel among the cylinders of the power unit. Cleaning the throttle valve may be necessary when the car shows the following problems:

• at idle speed when the engine is warm, the tachometer needle floats, changing the speed range;
• on an automatic transmission, jerking becomes noticeable, especially when switching from first gear to second;
• fuel consumption increases - often the engine begins to consume 10-20 percent more gasoline;
• Certain tremors appear at idle speed or when the unit operates stable at the same speed;
• the engine pulls worse, there is a delayed reaction to pressing the gas pedal or the car “chokes”;
• Dips may occur (most often on a manual transmission) when accelerating.

Such symptoms obviously will not please the car owner, because the vehicle begins to behave unpredictably, and also consumes much more expensive fuel. Therefore, in such a situation, the car owner often goes to a service station, where they are happy to perform a huge range of work to replace all filters, clean all modules and peripheral devices. In fact, it was enough to clean the throttle valve, but no one will tell the motorist about this. You understand that the service station business is specific.

How to flush the throttle valve yourself?

Despite certain difficulties in performing this task, it is quite possible to wash the throttle valve with your own hands. To do this, just read the normal manual for this process, as well as acquire all the necessary materials and tools. The process of flushing the throttle body will look different on different cars. For example, on carburetor cars it is much easier to complete this task, but the carburetor must be cleaned regularly. But in modern injection power units, flushing the damper is not so easy. However, nothing is impossible. To complete this task you will need to do the following:

1. remove the pipe leading from the air filter directly to the throttle valve;
2. Next, follow the instructions to dismantle the throttle - often it is enough to unscrew four bolts;
3. We put all the fasteners carefully in a box so as not to lose them, because purchasing them will not be an easy task;
4. To flush the throttle valve, you can use special products (for chokes or carburetors);
5. All internal parts should be washed until they are shiny, then allow the system to dry completely;
6. put all the components in place and carefully tighten the fastening bolts, then do not rush to close the throttle with the lid;
7. insert the key into the ignition switch and turn it to the stage of switching on the ignition directly, but without starting the engine;
8. Make sure the throttle valve closes completely after warming up (it will take 5-15 minutes to warm up).

After this, you can close everything with a clear conscience and test the car for changed parameters. In general, the procedure for cleaning the throttle valve takes about an hour, but the first time everything may take a little longer. The main task of the car owner is to correctly and accurately follow all instructions. Many people ask the question what to do if the valve does not go into place after the procedure. In this case, you will have to go through the process of “learning” the throttle valve, which is worthy of a separate instruction. But this process is best performed by specialists.

When is the best time to flush the throttle valve at a service station?

A service station today is not a motorist's best friend. Due to the huge number of these companies and the incredible competition, they try to squeeze everything they can out of the visiting driver. That’s why there are even legends about some service stations. The client came to change the oil and left with a new engine. However, in some situations it is impossible to do without the participation of a professional company. In particular, it will be very difficult to clean the throttle valve yourself if the following features occur:

• the car is new, belongs to high-tech developments - in such a car you won’t even get to the damper;
• the car is under warranty - if you try to clean the damper yourself, you will lose warranty service;
• you are completely far from plumbing, you have never held a wrench in your hands - it is better not to experiment;
• at a well-known service station you were offered a more or less affordable price for flushing the entire fuel supply system;
• Not only is the valve clogged, problems also arise due to poor functioning of the injector;
• you simply do not have the time or suitable space to perform the procedure yourself.

If you don’t have the time, tools or desire, it would also be better to pay specialists and get more or less high-quality services with some kind of guarantee. Of course, it’s not very pleasant to talk about a guarantee from modern service stations, but the responsibility of the master to you personally is present. You need to choose a normal service station to get more advantages in completing your task. Only professionals should be trusted to work on your car. We suggest watching a video with the process of cleaning the throttle valve using different means:

Let's sum it up

Operating a car in Russia inevitably sooner or later results in the need for large-scale cleaning of all systems. If the throttle in your car is clogged, you should clean it and not spend 20% more money on fuel. By performing throttle body cleaning yourself, you will be able to see good performance results without any problems. If you outsource this process to specialists, be responsible in checking the machine after providing cleaning services.

Often the symptoms of a clogged throttle valve are repeated when the injectors are not working properly. Due to the accumulation of various contaminants, this unit ceases to function normally and spray fuel. A stream of gasoline flows from the injector, which does not burn completely and significantly increases the cost of refueling the car. Therefore, when cleaning the throttle, you may also need to wash the injector using professional equipment. Have you ever encountered the problem of a clogged throttle valve?
