How to clean the engine throttle

Engine cleaning method: 1. First remove the intake throat to expose the throttle valve, remove the battery cathode, turn off the ignition switch, and turn the throttle valve upside down and straighten it. For the deep inside of the throttle, you can use a small amount of "carburetor cleaning" to clean it, and the unreachable place needs to be carefully wiped with a rag. 2. After cleaning, reinstall according to the steps just removed. Then start the initialization of the throttle, because the computer will remember the throttle opening. If there is sludge blockage before, in order to ensure air intake, the computer will automatically adjust the throttle opening to make the air intake reach a normal state. 3. Check whether the throttle valve keeps its original opening after cleaning. If the intake air is too large, the engine may shake when starting, and there is no acceleration force. The engine fault indicator may also illuminate.
