i'm having a real hard time diagnosing this problem with my teg. it has a real hesitation issue under 3000 rpm. the problem doenst exist above 3000 rpm. it aslo doesnt seem to occur until after the car has warmed up. i will push my foot on the gas to accelerate and i can feel the car holding back. then all of the sudden it will jump and will start to accelerate like normal. no CEL's or anything. i've replaced the wires, plugs, cap, rotor, fuel filter, air filter has just been cleaned, i tested the coil and the ohms are with in spec. i'm not sure where else to check. i'm open to ideas.

here's a few other things about the car, 169K miles on it, about 90K on the motor, i replaced the entire exhaust 2 years ago, new cat, both new o2 sensors at that time.
96 gsr

have you tried checking your ignition timing?

does this happen in all gears? say rolling at 30mph in 4th gear? Automatic?

how does it idle?

idle is real good, 750+/-, and i cant say for sure if it happens in all gears. its most noticeable in 4rth and 5th under 3000 rpm

do you have a gsr tranny or an ls?

double check the gaps on your plugs and if those check out try advancing or retarding your timing... it pretty much has to be one of those
