Volkswagen washes the throttle and does not pull the plug. Do you still need to reset?

Hello, there must be a match. First of all. This has nothing to do with whether we pull the plug or not, because after we clean the throttle. The carbon deposit is gone. The memory position before the throttle is relatively large because of carbon deposition. If it is cleaned, then she will turn on the throttle in the original memory position. At this time, the air intake is large, and the idle speed will increase. I hope it helps you.
