The throttle is dirty. Does it consume gas?

In the initial stage, the dirty throttle is characterized by unstable idle speed at the start or the engine speed drops to 500 rpm when braking at a red light, and the engine will occasionally stall. If it is serious, don't get on the bus, and the fuel consumption will increase. The engine fault indicator lights up. When the accelerator of a car becomes dirty, the following symptoms may appear: 1. When the throttle is dirty, the most obvious phenomenon is that the throttle is stuck and heavy, the speed increases slowly, and the idle speed reacts slowly to the throttle. As soon as the throttle is released, the speed will decrease immediately; 2. At the same time, it will affect the accuracy and smoothness of engine air intake. One of the most obvious problems is that it may lead to idling jitter or even flameout, and the growth rate of the fuel filler door is not smooth; When the throttle is dirty to a certain extent, it has already acted on the engine and needs to be cleaned. At this time, the self-regulating air intake of the driving computer will be inaccurate, and the work of the engine may be affected.
