Random stalling

There are very few differences between pre89 and 89+ GE electrical systems... unlike the GTE. You may go by that online manual and if you get hung up due to a discrepancy just ask.

I suspect either a bad EFI relay or a bad AFM. Try testing them both after heating them up with a hairdryer.

Another possibility would be a problem with the fuel pump relay and resistor pack. You can bypass both at the harness to test if this is the case.
