Throttle damage: 1. In the process of refueling, the throttle may be blocked, feeling heavy and the speed will slow down. Idle step on the accelerator, the speed rises slowly and the response is slow. In addition, loosening the throttle when driving will lead to the pollution of the automobile throttle, which will further affect the accuracy and stability of the engine intake. This is one of the most obvious problems. Idle speed may cause jitter and flameout. The throttle speed is not stable. 2. Generally speaking, the cleaning cycle of the throttle valve is about 20,000 kilometers. But the specific cleaning cycle depends on the car condition and driving habits. 3. If the road conditions are not good in the middle or you often drive at a low speed, you should replace the throttle as soon as possible to avoid more serious failures of the vehicle.
