yes you definately sound confused
as above, all comes down to year model/mods etc...
better description of the problem wouldn't hurt either mate.

Air flow meter (AFM) is usually I good place to start. Does the car feel like it is surging with the power coming on and off, with a hesitation in power delivery at part throttle? A bit rough coming on and off the accellerator? Using more fuel than normal? Is the car ok to begin with, then gets worse as it warms up while driving?

As the guys said, give us some more details (using proper grammar) and we might be able to help you out.

yeh mate i would check out the afm, i had problems around 4000rmp it would hesitate and jerk and then pull like nuts. Also when i tried to launch, with my foot planted the car wouldn't move just role then it would take off like crazy. My cousin in his riced civic would beat me on takeoff. Yeh i'd say sounds like afm.

AFM/Fuel pump would be the two large contenders imo.

ok its a 95

with a vf34
walbro fuel pump
custom cool air intake
TMIC bar n plate
i think i might have some with 2 do with air flow meter???
becoz its getting more but its still the stock 1???

try fuel blockage, wastegate stickage, rags in the intake, not bumping the nitrous switch or bad airlines to the wastegate
