Whats up guys, i been reading around here for awhile, but i cant seem to pinpoint my problem. my car is having some random misfire codes being thrown, but it only seems to happen intermittenly

I know its probaly the optispark, but how do i know before tearing it down?

thanks alot

does the car actually misfire or back fire or stutter or stutter at high rpm ?
