Slight Hesitation

[vettn71]

When I accelerate, mostly at low speeds. I don't feel it at higher speeds, but I guess it could be there. New FIC injectors, new GM (from White Racing Prod) PCV connector, car runs and idles well except for the hestitation

Thanks for the help

Okay, we are not talking about 2* port throttle "tip in" right? This is just the run of the mill hesitation when applying moderate pedal pressure?

The FSM lists:
Fuel pressure/ contaminated fuel. ( fuel filter okay?)
plugs & wires. ( and I guess coils too? )
TPS for binding or sticking.
Alternator output okay. less that 9v or more than 16v is a problem.
Ignition module ground, CKT 453.
Purge canister operation, chart C-3.
primary injector balance test
