So today filled up my car with gas and started it and boom the dreaded CEL. So I got home plugged in my tuner and it sais cylinder 1 misfire detected. Now I doubt there's anything wrong since it's got 10k miles. I'm assuming that I either got bad gas from Speedway or my cam tune just happened to make it misfire. It's not really a big deal, so I cleared it and I guess I'll see later if it comes up again. What do you guys think it would be?
