Check engine light comes on when the gas tank is below 1/2. Replaced gas cap and that seemed to help for awhile, but its doing it again? Any ideas?

    Have you had the computer checked for codes? If not, I would start with that.

    A computer code helps you know where to start testing.

    Some of the retail parts stores will check your codes for free.
