What is the low idle speed after cleaning the throttle?

Good afternoon. When a car steps on the accelerator in use, there will be carbon deposition in the pirated part of the accelerator for a long time, which will hinder the normal circulation of air, unstable idle speed and difficult acceleration. At this time, it is necessary to clean the throttle and electronic throttle, which generally need to be matched. It turns out that the computer board has recorded the idle air intake many times after the carbon deposit is cleaned, but the computer board still controls the air intake at the position when it is not cleaned, so it is necessary to use a decoder to match, so that the initial throttle signal can be remembered by the computer, and the normal fuel consumption takes several days to adapt.
