What will happen if the throttle does not match after cleaning?

The following is about "What will happen if the throttle does not match after cleaning?" Related introduction:

If the throttle valve does not match after cleaning, the following consequences will occur:

1. Matching means that the minimum closing angle of the throttle valve itself has been restored to the standard value after the throttle valve is cleaned, but the original correction value is memorized in the computer and must be deleted from the computer to restore the standard control data. If the matching is not good, the throttle responsiveness is poor and the idle speed is high;

2. After cleaning the throttle body, it is best to use a diagnostic computer for initialization. Many models can also manually match the throttle body. After matching, the idle speed is stable and the fuel consumption is the most economical. If there is no difference between the observed idle speed and that before cleaning, the engine works normally without any problems.

Because the computer has memory function, it has adapted to the state of the throttle before cleaning. After cleaning, the change of throttle opening (even small) is directly transmitted to the computer, and there are two signals. Common phenomena are high and low idle speed or high idle speed, so it is recommended to use a detection computer to match. The above generally means that the throttle has not been cleaned for a long time.
