While driving home today, (actually my freind was being the DD I was driving shotgon (golf is fun) the CEL went off at him. He was not reving it high or anything like that, just driving normal. Anyways, it went off and we stoped at someones house, and when we got in the car, the cel was gone. Will the ECU save the code and the paperclip trick work? I really have no clue what the CEL coul d be about.
