Is it necessary to clean the throttle for 20,000 kilometers?

The 20,000-kilometer maintenance suggestion is that the throttle valve needs cleaning, but there are also cases where it does not need cleaning.

Cleaning is not required in the following cases:

1, because the throttle is the throat of the car, the mixture can not be completely burned, and carbon deposition will inevitably appear in the throttle. Since carbon deposition will occur, it is natural to clean it up in time.

2. If the car can be used normally and there is no idling, jitter and slow response when stepping on the accelerator, there is no need to clean the accelerator.

3. The next time you need to clean the throttle, you can clean the carbon deposit in the air inlet, fuel injector and cylinder together, which can achieve the cleaning effect without wasting money.

4. Similarly, the three-way catalytic converter does not need cleaning. As long as the car doesn't break down, it is suggested that it doesn't need to be cleaned all the time. Unless there is a fault code, or the automobile exhaust is not enough, it can be cleaned.
