What is the effect of mismatch after cleaning the throttle?

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 response is poor and the idle speed is high.

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 idle speed and before cleaning, the engine is working normally and there is no problem.

Because the computer has a 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 detection computer to match. The above generally means that the throttle has not been cleaned for a long time.

Method 1, of course, is computer-matched, but some models are not. 2. Find out whether the accelerator fuse is broken or the negative battery is broken. Step on the brake and keep it for a few minutes, or go out for a run. Basically, normal idle speed can be restored.
