Thanks for the responses!!! I really appreciate this invaluable info!!!!

I took a look at the wiring and took it to another shop for another diagnosis. Wiring around the actuator seems good to go. However, at the shop, they cleared the codes and ran another diagnostic and are saying there is now a possibility, the crank sensor needs to be replaced. How can I tell the difference between having to replace the crank sensor and the throttle actuator?

I had one dealership tell me the problem was cruise ctrl sensor and ETA and now another shop is now telling me they don't think it was either one, they thinks it could be the crank sensor. Both ran diagnostics. I'm now really confused.

Any idea how I can tell the difference? The car will idle forever when not being driven, but loses power and decelerates to nothing after driving it for 5-10 minutes.
