spark shoud go every other “crank” of the motor…
spark_spark_spark…the two outer cylinders fire in unison, and the two inners fir in unison. so every other rotation of the motor should spark the plug your testing.
as for the coilpack, you would have a CEL, same for IAC or MAF. if you want i can run your codes over the weekend with my SCT scan tool and pull up any codes for you. try signing up on a ZX2 forum, becuase if its a common problem chances are there is a sticky or something for it and how to fix it. for shits and giggles why not CALL the dealer and ask if you could speak to a tech for a few moments, and explain whats going on and your thoughts.
