Slight stumble off idle.

94-95 PCM I just yanked off my MSD box replaced my coil and went back to stock ignition, I also replaced my 02 sesonrs with some delteqs (no more bosch crap).. The car for the most part runs better then it ever has, it doesn't die when I come to a stop when hope, it runs very smooth now throwout the power band, is really torquey, and shows no issues under WOT, but with that said.

Sometimes if I say double pump the pedal to quickly while driving it will have a slight stumble, or if if I give it just a little gas off idle (ie pulling away from a light), it stumbles for a second, then if I let off and gas again it smooths out.

It almost feels like a carb flooding, then clearing out when I open up the blade more to give it correct air.

Any thoughts or suggestions of where to look would be appreciative.
