97 GMC seirra
I have a problem when it's idling it fine when I go to drive it it wants to stumble or hestate. Now a week ago I cleaned the throttle body and the plimu was a little loose so I tighten it. Then for a whole week it drove fine now it starting to do it again.

Has anything come loose again? Is the check engine light on? Have you checked for vacuum leaks and the fuel pressure to the engine?
