Re: 1985 Eldorado Engine Stumble & Surge

I don't know about the part numbers, but the ECM uses the pulses from the distributor module to cycle the injectors. You may have to bite the bullet and get an overhauled GM ECM instead of an aftermarket type. I've replaced two this spring in Chevys, from Advance Auto Parts, and they work normally.
