The dirty throttle of air conditioner leads to inflexible throttle, and the air entering the engine carries a lot of impurities, which affects the normal operation of the motor and reduces the working power of the engine. In severe cases, the idle speed is unstable, it is difficult to start, and the power drops. Throttle is a controllable valve that controls air to enter the engine.
