Many car owners notice that over time, the car's speed begins to fluctuate, the engine starts poorly, some vibration appears at idle, and the speed starts to freeze - all this can be associated with contamination of the throttle valve and its channels. Due to the adhering dirt, the valve begins to close poorly, jams, bites... STOP, where does the dirt come from?
The photo below shows dirty throttle valves of various car brands. Here it is that resinous, sandy, oily mud!

So, cars use a closed-type forced crankcase ventilation system to reduce emissions into the atmosphere. This means that during operation a small amount of oil and gas vapors fly from the engine crankcase from the combustion chamber, and also a small amount of dust passes through the air filter (especially a dirty one), and all this forms an oil-dust flow that settles on the walls of the intake manifold and throttle valve. Over time, this plaque only accumulates. There are other factors that influence throttle valve contamination, but we will focus on the fact that on every car, sooner or later this unit becomes dirty, and there is no escape from it. Therefore, just like any car undergoes scheduled maintenance, the throttle valve needs periodic maintenance.
Well? Are we cleaning? Of course we clean! With what?
With this, ordinary carburetor cleaner!
We clean with a brush, do not spare the cleaner, and blow with compressed air.

Well, okay, we cleaned everything, blew it out, dried it, tightened it, installed it and. Did you forget to check the air filter? Usually, if the throttle is very dirty, then the air filter is also in poor condition. Be sure to check the filter to make sure it doesn’t look like the one in the pictures below.

Well, okay, the filter was replaced, all the clamps were tightened, we looked at everything again to make sure that all the sensors were connected, all the hoses were connected. Are we launching? Drin-drin-drin. started up, rejoice
