What's the effect of dirty throttle?

The following is about "What's the effect of dirty throttle?" Related introduction:

Dirty throttle will have the following effects:

1, the throttle is like a person's throat. If the throat is blocked by a foreign body, breathing will naturally be uncomfortable. Cars are consumables. With the use, the throttle valve will inevitably be affected by carbon deposition or oil pollution generated internally, which will lead to engine air intake problems, and at this time, the vehicle will produce some adverse reactions.

2. For example, the fault light gives an alarm, the idle speed is unstable, the acceleration is weak, the fuel consumption increases, and the exhaust gas exceeds the standard. When the above situation occurs, the throttle valve needs to be cleaned;

3. When the throttle is dirty, you will feel that the throttle is stuck heavily and the speed is slow. When you step on the throttle at idle speed, the speed rises slowly 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. An obvious problem is that it may cause idling jitter or even flameout, and the throttle speed is not smooth.
