I know your problem was allready fixed.. but I was kinda curiose to find out what it was. Because my check engine light was coming on when I first bought my car also. I took it in, and they said it was a faulty ignition (that someone with them ugly huge key chains had let it hang from it for too long) and they fixed it.. (for 390 bucks) the check engine light is off, but my check oil light is on now. Its not low, I've allready checked and had it changed, tho it didn't need it. If anyone's got any useful information... I would really appreciate it!
Seems I don't really wanna spend 400 more bucks.
