Truck in question is in sig.
After the truck has warmed up and your just cruising at a steady speed, say 35mph with light throttle, it almost feels like the engine just very briefly has a cylinder drop out but it's very slight and hard to feel. It almost feels as if your pulling a trailer and getting that "push" from the trailer but it's not that severe and only feels like the engine is doing it. If you give it just a little more gas it immediately goes away. It'll return when you go back to the light throttle.
Engine overall is in decent condition. Tune-up less than a year ago (plugs, wires, cap, rotor, plug wires 7 and 8 have plenty of space between them), fuel pressure is good last time I checked it, no fuel leaking from FPR and fuel pressure did change when vacuum line was removed. Lets see, what else... TPS is about 2 years old, ECT and IAT seem to be reading right with my scanner hooked up, O2 sensor is about 1.5 years old... Only thing I noticed with puzzles me is the computer constantly going from closed loop to open and constantly switching back and forth.
I'm going to ponder on this some more. If anyone needs more info just ask and I'll supply it.
