The cleaning price of the accelerator of Buick New Regal is generally around 200 yuan, and it is generally recommended to check or clean the accelerator every 20,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

The throttle valve belongs to the air intake area. At present, the work of each piston of the engine is not synchronous. When the engine is turned off, the intake valves of some cylinders cannot be completely closed, and some unburned fuel is constantly evaporated and oxidized, which will produce some carbon deposits in the intake pipe, especially behind the throttle.

On the one hand, these carbon deposits will block the idle channel and make the throttle stuck or beyond its adjustment range; On the other hand, the wall of the intake pipe will become rough, and the intake air will produce eddy currents in these rough places, which will affect the intake effect and the quality of the mixture.
