I figured that part. When I say "truck" I usually mean van. In EMS, anything that gets you from place to place is a "truck". The reason why I asked in the F-series section instead of the E-series section is because there is a lot more knowledge to be had here. I figured that the same information that I gleaned here about F-series trucks would work for E-series vans.
As some one posted earlier, it *should* work to use a newer (van) PCM in an older van, provided it had split-shot injectors. I tried this today, and it did in fact work. The only thing that is a little screwy is that the newer truck has an intake air heater, whereas the older one does not. It throws a code, but it doesn't set the MIL. I can live with that.
It remains to be seen if this actually fixes my original problem. One positive sign is that all the codes that I got from the old PCM continuously didn't appear when I ran the truck with the new PCM. The only code I get now (a new code I've never seen before) is for the "Intake Air Heater Low Input), which makes sense since in '98 they didn't use them.
