Ever since the first day i got my cobra it had the check engine light on, the dealership that had it didnt have clue what was wrong and took a huge chunk off the asking price(worked for me). It seemed to run good for the first few days i had it then i started noticing a rough idle every once in awhile while sitting at stop lights and would sometimes have to fight to keep it running. My best guess was that the o2 sensors were acting up since it has an aftermarket exhaust and cats. I just got a bama tuner hoping it would fix the problem and get rid of the check engine light. First off i plugged it in and set it to the street tune(87-89 octane), it loaded up everything alright. Next i started up the car and it did the rough idle thing it likes to do and died. I started it back up again and revved it a little, it did seem more responsive and had the check engine light off though. Any suggestions on the dying issue? maybe tune the fuel/air mixture?
