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

It is best to do computer matching when cleaning the throttle. At this time, the computer is based on some relevant data of the throttle before cleaning. If it does not match, it may cause problems such as increased fuel consumption. 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.
