Started the car this AM and let it warm up for a while. It was/is 20* outside. As soon as I got in and touched the gas the CEL came on. Now I have not even done a single thing to this car except drive it and fill it once with Mobil 93. Maybe the gas I thought. I filled it again later on this AM with Sunoco Ultra 93 and the CEL stayed on. Car is running fine and I got 19.6 on my first fill and 21.8 on this last one. This is with no heavy hot rodding around because the thing has no miles on it yet. So........how many of you guys got a CEL on your stock new cars??
