misfiring under load!!! Any idea's
I have a 04 ZX10r it has a misfire over 9000rpm almost like a fuel cut or ignition cut it does not do it all the time it almost trys to accelerate through the revs but not quite.
It has had a little work has been 1050 race inlet and exhaust cams full yoshi and pc3 has been running great for a while but now spat its dummy at me.
Have replaced the plugs and tested the coil packs for spark all check out fine checked all the compressions and the wiring connections all seem fine, seems like a cut of some sort, any idea's
