What happens when the throttle valve does not match well after cleaning?

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. Either with a computer or going out for a run, there is usually a self-study function, but the idle speed may be too high during the study. If you can overcome it, you don't need a computer. If you wash the accelerator yourself, most cars still recommend driving by yourself. After all, matching costs money. You can also buy a software online and equip yourself with a diagnosis interface. Personally, I think it is unnecessary.
