How to clean the accelerator of a car?

During the operation of EFI engine, a small part of exhaust gas generated by combustion in the cylinder will generate carbon deposit at the throttle body through the intake valve and intake pipe. In addition, after the air passes through the air filter (especially the air filter that has been used for a long time), impurities will remain in the throttle. These pollutants will accumulate and take a long time. When the engine idling is unstable, pay attention to cleaning the throttle. The method of cleaning the throttle valve is as follows: 1. Loosen the fastening screw of the air cleaner and the metal clip of the throttle body with a flat screwdriver to separate the top cover of the air cleaner from the throttle body. 2. Keep the throttle closed, spray carburetor cleaner around the door, and then wipe it carefully with a paper towel and a small plastic pad. Check whether the throttle valve is clean and can be opened and closed freely. Then connect the air filter to the throttle body and connect it in place to ensure sealing. Tighten the screws of the metal clip. 4. Note: Do not unplug the throttle position sensor of the automatic transmission, which is on the throttle body; Otherwise, the position of the accelerator pedal needs to be reinitialized with the instrument; Be careful not to spray carburetor cleaner on the filter sealing skirt in the empty throttle body, which will corrode the skirt and affect the sealing performance.
