Re: Diagnosing a misfire

First go get you one of those infared laser thermometers then Let it run and get up to temp then shut it off and check each exhaust tube they should all be fairly close in temp if you have one that is way off from the others that will be your cylinder that's not right, then from their your only having to diagnose one cylinder instead of 8
