I just had the fuel cap, filler neck and seal repalced on the stang and the "check fuel cap" keeps coming on...then the "Service Egnine" Light comes on. The car was checked for leaks and passed. Car gets reset and it drives for about 2 miutes and the light keeps coming on after everything I try. I heard that after the 1999 Ford no longer had this "check fuel cap" lights put on the car. Anyone have this problem? Anyone take their stang to the dealer for something like this? ANY HELP WOULD BE GREAT!!!!! Thanks.
