I have an 05 jeep wrangler with a 4.0. On each fill up the check engine light comes on. The gas cap is on tight so I know that is not the problem. I can reset the light and most case the light will stay off until the next time I fill it. Does anybody know what the problem might be.

It would be easier to make suggestions if we knew what code is being thrown. The next time the light comes on use an code reader or read it from your dash by turning the key on (not starting the engine), off, on, off and on again and it should display the code.
