Will the dirty throttle affect the engine?

When the throttle is dirty, the most obvious performance is that when the car refuels, it will feel that the throttle is stuck heavily and the speed will be slow. And when you step on the accelerator at idle speed, the speed will rise slowly and the response will be slow. Release the throttle and the speed will drop immediately. It also has a direct impact on the accuracy and smoothness of engine intake. The most obvious problem is that it may cause idling jitter or even flameout, and the fuel valve speed is not smooth.
