strange at certain RMP'S
at ~ 2200rpms my acceleration dies and then pics up at higher rpm. this has nothing to do with throttle position and just always hapens @ about 2200 rpm and then before 2600rpm the acceleration pics up again there is so much lac in acceleration that i can feel it and i can see it on the passengers head when it stops pulling back and goes forward and then goes back again when the acceleration picks up.
anyone have any ideas of whats wrong?
