I have a 2011 chevy Silverado with a 4.8 vortec v8 this is a fly by wire truck.
So I pulled my throttle body to clean it. I had 5 engine codes
One was tps high voltage
One tps low voltage
One tps failure
One fuel trim bank 1 lean
One fuel trim bank 2 lean
I pull the throttle body and clean it extremely well with carb and choke cleaner.
By doing this I moved the butterfly plenty of times unaware that you shouldn't move it I even played with it like a dummy.
so now I have a iac code p0507
and my truck is sitting at 3k rpm in park and neutral.
I believe I need to do a relearn idle process but I don't have a tech 2 scan tool. I'm told driving it 150 to 200 miles will allow the ecu to reset itself. So I'm at 100 miles now.. Should I just wait it out or take it in for the relearn?
have the same problem?
