1994 Pontiac Transport: Engine starts and idles great but when put under load it misfires and misses out horribly! Im lost. Ive replaced plugs and wires. It has new ignition module and coilpacks. New Crank position sensor. New fuel pump and filter. What else could there be????

I had a similar problem that went back to the PCM. Is there a way you can swap that out (if you have a spare?)

Powertrain Control Module=computer that controls everything. Located under passenger side dashboard, under kick panel.
