What happens when the throttle is dirty?

When the throttle is dirty, the following phenomena will appear: 1. Throttle pollution will lead to congestion and heavy feeling, which will slow down the car. At the same time, when you step on the accelerator at idle speed, the speed rises slowly and the reaction slows down. After you release the throttle, the speed will drop soon. 2. Throttle pollution will also directly affect the accuracy and stability of engine intake. One of the most obvious problems is that idling may cause shaking and flameout, and the speed of the refueling door is not smooth. 3. If the throttle has been polluted to a certain extent, which affects the work of the engine, it needs to be cleaned. At this time, the self-regulating air intake control of the driving computer may be incorrect, and the action of the engine may be affected.
