What are the hazards of throttle mismatch?

[MarcusFitz]

The hazards of throttle mismatch are: the engine idle speed will be very high, and there will also be unstable idle speed. After the idle speed is too high, it will cause the engine fault light to come on, making normal driving impossible. Matching means that after the throttle is cleaned, the minimum closing angle of the throttle itself has returned to the standard value, but the computer still remembers the original correction value. The memory in the computer must be deleted to restore the standard control data. The throttle is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. It is connected to the air cleaner at the top and the engine block at the bottom, and is known as the throat of the automobile engine.
