What are the manifestations of Magotan's dirty throttle?

The dirty performance of Magotan throttle can be divided into the following three aspects: 1. The performance of the throttle when refueling: the throttle is heavily blocked, which leads to the slow speed. When idling, the speed rises slowly and the response is slow. 2. Problems caused by throttle pollution: Throttle pollution will affect the accuracy and stability of engine intake, mainly manifested in shaking and flameout at idle speed, and the speed increase is not smooth. 3. Cause of throttle pollution: There is a lot of dust around the air inlet in the vehicle running environment, and the type of engine oil is not suitable, which produces a lot of steam and impurities. After the flameout, the throttle cannot be completely closed, and the dust at the air inlet accumulates more.
