I have just gone through exactly the same problem! I replaced MAP sensor, ignition modual, fuel pressure regulator, distributor, and coil. Also checked for any bad vacuum lines or bad grounds! After many suggestions I said hell the only thing I have'nt replaced...you guessed it, the computer and that finally fixed it. All of those things that I replaced according to the Hayes manual could have fixed the problem but didnt. I did not have any diagnostic equipment so it was the manual and a couple of friends to help. I hope this helps.
