Check engine light comes on when gas cap is removed to refuel
I've had this problem in my 89 coupe for a while, to reset and clear the check engine light I remove the negative battery cable. light stays off until next refueling is there a seal problem below cap , I've replaced the gas cap, problem still comes back, is there a pressure sensor switch some where?

If you do not tighten your gas cap sufficiently, (three clicks minimum) the Service Engine Soon light may come on.
It's caused by excessive EGR flow. What codes are being stored in your ECM?
