Hi witghtmog,
Sorry to hear about your pain, the truth is aging engine management systems can be challenging, it may sound extreme but I'd recommend investing in a good modern aftermarket ECU.
If your engine/ECU loom is in good shape, a plug and play install would be the way to go, you just need the pin in/outs and a patch cable can be made allowing you to simply plug in the new ECU to your existing loom.
I did exactly this with my Duratec Plus 4 using a plug and play EMU Black ECU from ECU Masters.
