either the throttle body or the pedal sensor is bad. you need to have it checked to verify

Even though both were brand new parts, the thottle body was replaced yesterday, and the app sensor about a moth ago.

The parts came from orileys i was wondering if not being oe would that have anything to do with it also the evap purge valve is loose think o ring may be worn down im just out of ideals

i would use only gm parts for that repair.
evap issue has no effect on this system.

ok, still would only go with gm original. had no luck with aftermarket parts.
get it checked at a shop to confirm. make sure all connectors are clean and tight
