Do you need computer matching after cleaning the throttle valve?

The pilot throttle needs to be matched after cleaning. If the throttle does not match after cleaning, the following symptoms will occur: 1. Matching means that after cleaning the throttle valve, the minimum closing angle of the throttle valve itself has returned to the standard value, and the original correction value memorized in the computer must be the memory in the computer. Delete and restore 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 idling, the fuel consumption will be more stable and the most economical. If there is no difference between idle speed and before cleaning, the engine is working normally and there is no problem; Because the computer has memory function, it has adapted to the state before the throttle cleaning. After the throttle is cleaned, the throttle opening changes (even a small change), which is directly reflected in the signal on the computer. There are two common phenomena: high and low idle speed or high idle speed. Therefore, it is recommended to use a detection computer to match it. The above generally means that the throttle has not been cleaned for a long time.
