Thread: 04 gtp cylinder #3 missfire

Well what have you done to try and fix it?

Have you done new plugs?

Have you switched coils to see if the misfire follows, did you do the same for the injector?



And

My dad has been a mechanic all his life and says if you can hear it missing out the exhaust its def a valve.

Of course you can hear a misfire out the exhaust, but that doesnt always mean its a valve. Like where else can the noise go???
