slppy is right. it is usually an individual cylinder misfire. IIRC, the CEL will flash and you can count the flashes which will tell you which cylinder is misfiring. I don't know if that's true or not; I just use a OBD2 scanner to tell me what codes I have.
Hey well i was driving my Z and all of a sudden my check engine light started flashing then i would atay on then flash again. on and off o and off. damn what can it be. plase help!!
i have the same prob. the only code i get is p0300. i troubleshot it down to all my driver side cylinders were not firing! i changed the cam sensor, checked the coils, plugs and injectors. everything check out good. the next thing i need to change is the crank sensor.
Simplest problem is a fried coil pack. Let it idle and unplug/replug each coil pack one by one. If one of them being unplugged doesn't affect the idle, that is your bad pack/cylinder. Other than that it could be anything from wiring issues to a bad injector.
