After removing the throttle, the idle speed becomes unstable.

What you should say is slight instability, common problems. There was definitely no such phenomenon before washing. The solution is to go to SSSS store to reset it, and then run it for a few days to set it up. It will be fine in a few times. The way the battery is disconnected is handled by a small repair shop. It is slowly restored by using the automatic learning function of the computer. The instrument is computer refresh and throttle reset learning. It is also recommended not to move the throttle and intake system easily, because washing for too long will cause problems.
