Ok so i looked around to find a thread about what's happening to my car could not find one. OK so my car is a 92 civic HB with a built GSR. With cams valve train and jdm itr pistons with all the bolt ons you would see in a normal set up. On s300.

So my car is hesitation/misfiring when I shift at high RPM when I engage my clutch going into the next gear. For the first second of accelerating in the next gear it hesitates. when I shift fast at low RPMs it's fine but not at high RPM. and it pulls nice and hard from 1500 RPM to 8800 RPM
