Engine Light keeps coming on on 2007 Chrysler Aspen

My engine light came on a few weeks ago...someone told me to check my fuel cap to make sure it was on right...sure enough when i secured it again the engine light went off...now my engine light keeps coming on again and even after I check the fuel cap for tightness...the engine light still stays on...had an oil change done a few weeks ago and they did a diagnostic check and it seemed to have checked out...it starts and drives fine with light on...can any one give a help on this?

well, if they did a diag check, then it could not have checked out if the light was on. the check engine light has over 15oo codes. the chance of you doing a gas cap and fixing it is remote. get a real diag and find out what is going on. Roy
