Agree with z51vette.... betcha it is the gas cap and in fact if your C6 is a 2005-2008 (I think I have the date span correct) GM was replacing faulty gas caps and those caps caused the check engine light to come on...

Run it down to Advance Auto or any other auto parts store and they will read it and can clear it for free. If it's nothing important you can clear it out and see if it comes back. Rather get it checked for free than whatever nonsense the dealer can come up with. Plus you know well in advance if there's going to be a problem.
