I had the same problem with my engine light coming on. I have a 1996 twin turbo. The light came on almost every 25 to 35 miles. I was told I needed a top end rebuild. I discussed with my mechanic at CB Foreign cars and decided that I would try a tier one gas such as Shell Premium. During the first tank the light came on when the tank was 1/2 full I reset it with my obdII and since then it has not come on in over 1000 miles. I would try a top tier gas before a rebuild. Bob Kalb
