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.
