    If its not one thing its another

    k, installed a nitrous kit and went out to get it dyno'd. my tuner wanted to do a few motor passes before we used the spray. so first pass car puts down 395rwhp which is about normal for it on motor. second pass it pops really bad once it hit 5krpm so he lets off. no misifres showed up and a/f is fine. so we do one more pass and no popping but car put own 315rwhp. hes thinking it has to do somehing with ignition anyone have any suggestions. thanx Aaron.

    and also, misfires only throw engine codes if it misses from the coil, if its a plug problem or a wire problem, it wont throw a code.

    i dunno how they do it, but they can pull up a diagnostic screen that shows each cylinder, with a zero on it, and everytime you get a misfire, for whatever reason, the counter goes up on the appropriate cylinder, i dunno if you did that or not.

    more of a misfire sound my tuner did say its rare that the coils go bad on the cars. so i guess ill start with a plug and wire swap first
