Okay well then I am confident if you get it scanned you will have atleast a pending or history code in there. Something is going on.
OBDII systems (what you have) are very good at catching problems and tripping atleast a pending code (this will not illuminate your light). So get a code reader and scan away!
If not, you may want to look at things such as vacuum leaks, weak fuel pressure, oxygen sensor activity, MAP sensor parameter, etc.
