You may want to check to make sure that you gas cap is on correctly, usually a check engine light mean an emissions problem. Also, if you have recently added gas to your vehicle from someplace other than your usual gas station this could be a cause as well, bad gas. what you would need to do is either get the gas out or run it and fill it up. it will usually take a full tank of gas to get the light to rurn off. if this doesn't work, then you want to take it in the a mechanic. But my repair book for my 2003 impala tells us to take these steps first.
