2xls1, we GREATLY appreciate all of the work that you did for us. I'll have Dad pull the injectors and check the parts numbers. From what Dad said, the guy that sold him the truck was not very trustworthy. Dad is looking for a daily driver nor a race car. I think the prior owner was looking for a race car. Trust me, we have done so much to fix all the prior owners hacks. What you did is exactly what we wanted, which is get to a mostly stock OS that we can tweak with PCMHammer and TunerPro. Dad was delighted when we were able to get the S10's original speedometer to work and to control the electric fans with the computer vs. the finicky temperature switches.

I'll post back the progress we make to hopefully give you some satisfaction on how much you've helped, as well as what we find on the injectors. Thanks again!
