Is it necessary to clean the accelerator of the car?

It is necessary to clean the throttle valve of the car. If the throttle valve is too dirty, there will be more colloidal carbon or dirt around the throttle valve plate, and the cross-sectional area of the air passage will change, which will make the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin, which will lead to the car shaking. The steps to clean the throttle are: 1, open the hood and find the throttle of the engine; 2. Remove the air filter and intake pipe with a flat screwdriver, and unplug the electric socket on the throttle; 3. After removing the screw, remove the throttle, and then block the air inlet of the engine with a dry rag to prevent dirt from entering the engine; 4. Spray the cleaning agent on the throttle for cleaning.
