Default is my ECU bad?
long story short, my car has being developing a dead/1 rotor mis at random, happens mostly on light throttle and sometimes at idle, revs fine and accels fine through WOT. i scoped my injector signals at the ecu, and when the mis happens the front primary injector signal drops out completely, while the rear is operating fine. when i snap the throttle, the front injector starts working again.

the wiring is ok, as i tested and rewired the harness to fit in an FB chassis. 12v at all injector clips and >.1 ohm resistance from the clips to the ECU plug.

the ECU is an N326...

could my ECU have a bad injector driver? or is there some other sensory input to my ECU that i dont know of, that is making it drop the primary injector?
