How does Fengshen a60 throttle jump back and forth at 2800- 1800 after cleaning?

Don't go to 4s for cleaning. 4s is cheap 160 yuan. Just go to the garage to clean it. Very cheap. That's actually very simple. It is nothing more than removing a screw and spraying a cleaning agent. You don't need to dry it with a cloth, it's so hard.

There is a learning process after cleaning the electronic throttle, mainly because the clearance of the idle key has changed after cleaning, and the throttle needs to adjust the idle opening, which should be stable soon.
