Default Irritating surging/loss of power

So my car is a 94 gt with newly replaced fuel pump and filter, fpr, ignition coil, distributor, plugs and wires. I have checked my tps and the voltage sits at .96. I am using a digital multimeter so i am unable to tell if the transition is smooth but i could not seem to find any "dead spots"

So heres the issue: Once the car warms up it begins to studder/hesitate (whatever you choose to call it) whenever i am cruising and just maintaining my speed with very light throttle(maybe 10%) but once i give it a little more gas it comes to life. it is not throwing any codes whatsoever. I have searched and searched. I would just like to see if any one else has any suggestions. ANy help is much appreciated

check for vac leaks, make sure the maf is clean, all wires on tight at plugs and at cap, at dusk lightly mist wires with a spray bottle check for any arcing, if present replace wires, make sure plugs are good and no cracks for arcing to occur in the porcelien

only if it's partially stuck open or getting vac when it shouldn't, but then again a koer should pick that up as pinle position sensor has learned open and closed voltage positions in the KAM

is it possible that oil blowback into the intake could cause this? or possibly the pcv being bad or clogged?
