igntion/bucking and surging question
basically, its a 92 civic b16a swap
ive went through everything on numberous occasions, i have 2 b16a swap civics both 93-92, so ive interchanged damn near every part on them
here is the setup, second gen swap, iceman intake, stock everything else, reprogrammed ecu, (which i switched back to stock b series program) clutchmaster flywheel and clutch (erelavant) anyway back to the problem
it idles well, maybe a little low, nothing that i cant fix, but if you put the motor under any load (trying to move it, in gear) it acts like it wants to die, i have to let off then pedal it, does not accelarate like its suppse to
it had a previous problem which led to the headgasket going, so i changed that, and i found out i had first gen injectors( stole hers to make mine work), so i swap her over to second gen injectors, it has a fuel pressure gauge, which reads around 45psi, so thats good, timing is good, i changed over to del sol (SI) fuel pump for extra duties, and new fuel pump (maybe bad gas since it had been sitting)
plugs are black (leads me to believe RICH) which could be telling me ignition system isnt doing its job
has swaped wires, plugs, even distributors, with no prevail, maybe im missing something
i still need to compression test it, but im sure it has good compression, it idles to well not to have at least good enough compression(this motor doesnt even have 2000 miles on it, and already ive had to change the headgasket, and oil pump seal
long story but lets just say my girl didnt listen when i told her to baby the motor when its breaking in period
any help would be much appreciated

Does it start okay? When you swapped dizzys did you use the old coil and ICM? Have you checked the ECU ground? Fuel filter? (I doubt its that, but they are cheap)
it starts OK, maybe a little slow, which ive got the rotor, just need to change that,
when i swapped over distributors, i swapped the whole thing, fuel filter is brand new, i hope its just the coil going bad or rotor, but if its a distributor itself, that sucks, havent checked the ecu ground, can that cause that big of a difference, i use to run around the ecu laying on the floor, with no problem, on my car
thanks for the info

What I meant by ECU ground is the ground at the theremostat housing. It is a 10mm bolt check that. If you swapped everything in the distributer then you ruled out coil and ignitor.
Did this start happening when you changed injectors? Maybe one of them is sticking open or something. If you say all the plugs are black then you can rule that out too.
Have you checked your fuel pressure without vacuum?
