Hello,

 No my vehicle is a 1988 GMC S15 pickup. It has the 2.5L TBI engine. Im coming to the conclussion that they must not have made too many of these engines do to the fact that I have been searching the web for a good week now and the only info I can find is for the 2.8L and larger engines, but absolutely nothing on a 2.5L.. The 2.5L is a 4cyl and I believe that there must be a special way to set the timing, Im just not too sure what it is. I appreciate your help, its driving crazy trying to figure this out.
