Ok, kinda a stuipid question, but some of you have tons of experiance. I was driving the other day and my check engine light came on. Nothing has changed as far as sound, performance and I cannot find anything wrong. The only thing I have done to the car since I got it was tighten the alternator belt, but could that cause the check engine light to come on? Thanks! 

........ I've never seen anyone get a CEL from LOW Oil.
