Pontiac Problems? Ask a Mechanic for Answers ASAP
How's it going? Is the rev up the same issue the throttle body was replaced for or is it a new concern after replacement. An idle reset is what is normally done after replacement usually with a scan tool. Shoot me your Vin real quick and I'll check for another route. Generally though that's not going to cause that and there is likely a vaccum leak from something disconnected if this is a new issue.
