How often does the car throttle have to be cleaned and how much does it cost?

It is generally recommended that the owner clean the throttle every 20,000-40,000 kilometers, and the specific cleaning cycle depends on the personal car habits and car environment. Generally speaking, the price of throttle cleaning varies from place to place. The air door of 4S shop is clean in 200 yuan, and the workers outside are around 20 yuan:

1. The throttle valve is a controllable valve that controls air to enter the engine. In car maintenance, the throttle is also one of the daily maintenance, which needs to be cleaned regularly. It is usually recommended that car owners clean the throttle every 20,000-40,000 kilometers, but this is only a reference value for everyone. The specific cleaning cycle depends on personal car habits and the environment inside the car.

2. So it can be judged according to some phenomena of driving at ordinary times. If the car has unstable idling or weak acceleration, then you should think about whether the throttle has not been cleaned for a long time, because most of this situation is caused by dirty throttle. In this case, it is recommended to go back to the store as soon as possible to check the actual situation of the throttle and clean it well.

3. Generally, after cleaning the throttle, you must match the throttle data with the detection computer and reset the throttle opening, because the ECU (driving computer) of the car has memorized the opening when there is carbon deposit. If it is not reset, the engine will have unstable idle speed and high speed, which is even worse than before cleaning. Therefore, the owner had better not wash the throttle valve himself, and this part of the money can't be saved. After all, data matching can only be done with professional equipment.
