You adjusted the idle? Why? If it worked fine before, and didnt work all of a sudden, do you think it COULD be a part failure,not a adjsutment? I bet your check engine light is on. The computer is confused.
You can backyard Bob the adjustment after you correct the failed part. But, your computer has a small window of what it calls acceptable.
The only way to accurately adjust base idle on gems engine is with a Testbook.
Radio Code.... Each radio has a different code. Did you pull it out and give the dealer your Serial Number? They CAN look it up from that.
