How much does it cost to clean the throttle of Cadillac ATSL?

The throttle cleaning price of Cadillac ATS L is generally around 300 yuan. It is generally recommended to check or clean the throttle every 20,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. The throttle valve belongs to the intake area. At present, the piston of the engine works asynchronously. When the engine is turned off, the intake valves of some cylinders cannot be completely closed, and some unburned fuel will continue to vaporize and oxidize, producing some carbon deposits in the intake pipe, especially behind the throttle. On the one hand, these carbon deposits will block the idle channel, causing the throttle to stagnate or exceed its adjustment range; On the other hand, they will make the intake pipe wall rough, and the intake air will generate eddy currents in these rough places, which will affect the intake effect and the quality of the mixture, thus causing idle jitter, poor speed increase, flameout and fuel consumption.
