Why do you think you have to replace the computer? It sounds like the shop is having you replace parts without knowing what's wrong. I went through $800 the hard way like this in my '76 280 with a [email protected]#% mechanic (new computer, AFM, injectors, etc.) before switching to a mechanic who knows what he is doing. The new mechanic fixed that problem for $40. Turns out the idiot who I had install my MSD ignition installed it wrong and fried it. It still worked -- sometimes -- but was quirky and unreliable. All the good mech had to do was disconnect it and re-hook up the stock ignition system.

But I am not good with electrical problems and couldn't figure that out. Oh well, my fuel system is brand new except for the ignition module.
