Jetta, the throttle keeps jumping.

Hello. This situation is that the motor of the throttle itself is damaged. Or poor contact at the short circuit of the harness connecting the engine and the throttle valve will lead to this phenomenon. It is recommended to check whether the harness is short-circuited or flooded first. I hope my answer can help you when changing the throttle. Have a nice trip!
