Don't forget there is still an engine under all the electronics Put a vacuum gauge on it and see if you have steady or rapidly fluctuating reading (which translates to bad cam lobe or burned valve.) Otherwise, the only other thing I can think of is that if you removed the distributor at any point, you may have it one tooth off, changing ignition timing.

    Actual spark timing is controlled by "cam sensor" (hall effect unit where points would go inside distributor) Make sure that the mount plate has not become loose in there and is allowing timing to change as you drive. What vacuum readings do you have running? To eliminate stuff you need to verify it's OK!!!

Idles ok backfires thru exhaust under a load


Since it is so old, Start with a compression test. 90lbs is about minimal. The cylinders should be with in 10% of each other. If your there or lower, Time to retire or rebuild this engine. This part here will save you time, trouble and money into an engine that won't be any better when your done.
