What happens when the car throttle is dirty?

When a car refuels, it will feel that the throttle is stuck heavily, the speed is slow, the speed of stepping on the throttle at idle speed is slow, and the response is slow. Release the accelerator when driving, and the speed will drop immediately.

Unclean throttle will affect the accuracy and smoothness of engine intake. One of the most obvious problems is that idling may cause jitter or even flameout, and the throttle speed is not smooth. Unclean throttle will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of stepping on the throttle, reduced power, even difficult starting and increased fuel consumption.

With the increase of the number of kilometers, a certain amount of carbon deposit will be produced in the process of automobile use, and the throttle valve is a place where carbon deposit is easy to occur. With the increase of carbon deposit, the carbon deposit of the throttle replica will become thicker, and the throttle control is very accurate. A little carbon deposition will also affect the air intake of the throttle valve, making the air intake inconsistent with the requirements of the engine computer, thus making the engine burn poorly, leading to the decrease of engine power and the increase of fuel consumption.
