Service Engine light I just started my car this morning and for some reason my service engine light is on. Any of guys know why this would happen. It was fine over the weekend when I was driving it. It seems to be driving fine too. I remember this happened a couple of months ago and a few days later the light stop coming on. Maybe there's something loose

Yeah, and did you mod the car at all this weekend, did you get gas and not screw the cap back on 
check that. It's probably something small like that, or something with your EGR or the likes. If it is with your EGR or AIR, ditch that crap.

I'm pretty sure that there is a federal warranty on the emissions control system, 8 years/80,000 miles. Had to check on that for a friend who owns a Corolla and thats what they told me, don't know if its the same for GM. Anyways, it could be the passenger side cat or the passenger side o2 sensor. It wont affect performance but your car wont pass smog, you may be able to get this problem fixed for free. You should ask a dealer about it. Or use it as an excuse to throw some high flow cats and LT's on.........
