well when i first installed the new engine i still had the problem. since i had replaced the cap, rotor, plugs and wires when istalling the new engine i ruled that out. i also had a new fuel pump so that wasnt the isse. had a code of low voltage on tps, changed it and it didnt fix it. my buddy that work at the proving grounds told me to run 4 bottlrs of injecter cleaner in the tank, so i did it and with in 50-60 miles the studdering was gone, hasnt come back either. he figured it is the poppits dirty/clogged and said if the cleaner worked, that i should then take my upper plenum off and clean all of them by hand or get the upgraded spider. well i havnt done that as i havnt seen the problem come back, but if it does i will put the upgraded spider in.
