First try a hard reset. Unhook the negative battery cable for about 45 mins. Then try it. That's where I'd start.

Sure sounds like a lot of information is missing from your posts. For starters, you need to let the members know "IF" you got a successful DTC fault code(s) reset, You have to perform a successful T/B re-learn procedure so it can send back the correct sensor(s) position signals to the ECM. May also have to do the same thing for a pedal position sensor replacement.

I’ve done almost everything, I’ve reset the codes & did the relearn process at the dealership , that didn’t fix it & now I’m just stuck on it & need help

O'Reily auto parts is a retailer not a brand. The brand is given on the box and receipt. The throttle body is manufactured by one of two entities. Specific questions were asked and generic answers provided. May the force(s) be with you.

Where the boys are going with this, I hope, is these cars are very parts sensitive.
If you went to O'Rielly's and grabbed a generic throttle body instead of going to GM and buying an OEM throttle body that may be your problem.
Then there's the silver or gold blade question, there is a specific difference. What that difference is I cannot recall off hand.
Reads like you had a dealership involved for the relearn process, what did they say.

I wouild say go with BASG8 - Make sure you have the correct blade. make sure no wires are broken away from harness or the insulation of wire is exposing raw wires touching. Then make sure a competant shop RESETS the unit. relearning is done with starting , idling etc, . Reseting is program obd2 controlled. Make sure no air gaps anywhere from install.

Thread is located in the V6 engine tech (LY7) section of the forum. The V6 only has a gold throttle body blade. The V8 can either be gold or sliver.
