you and me both!! mine will run good, then it wont. i think i find the problem, but not.

dont rule out EFI. it aint perfect. you have actually added more fault areas with EFI. you now have wiring to each injector, you have the computer, you have engine data such as temp. RPM and maybe more that is being sent to the computer. (this is why i love CIS).
as with CIS, you have injectors and fuel pressures and air leaks. (part of my problem).

pull the plugs and check to see if any are different.

check AFR's. idle, cruise and boost.

valve adjusment.

check voltage at battery with engine on and a load. (lights etc).

did you run new wires to the coil and dist?

check grounds from engine to body and MSD and computer

i put an Oscope on my dist. i have not found what it should look like but it was a strong and clean 17v waveform. i considered my dist, but i would think that is a work or no work part....could be wrong.

if you are not running your O2 through the speed relay, you no longer need it. just bypass it to run the FP.
