What are the hazards of throttle mismatch?

The hazards of throttle mismatch are: the engine idle speed will be high and the idle speed will be unstable. After the idle speed is too high, the engine fault light will light up and it will not work normally. Matching means that the minimum closing angle of the throttle valve itself has been restored to the standard value after the throttle valve is cleaned, and the memory in the computer is the original correction value, which must be deleted from the computer to restore the standard control data. 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. Known as the throat of an automobile engine, it is connected with the air filter and the engine block.
