Hey guys...

So my H3 is coding the infamous Po302 #2 cylinder misfire...
Replaced the plug and coil. A few weeks back and cleared check engine till today when it coded again same PO302.

So the quest is whats next ? Orderd some fuel injector cleaner. Interested in what the brain trust here suggests...
Thanks !

 

Easy stuff first. Follow the wire harness to the #2 coil for compromise (frays, cracks or rubbing).

 

Thanks for that Doc...

Cheeked out or checked out good. Mixing up some Lukas stuff for the injector wash.

 

OK Fella's so its been a few weeks now and no more 302 codes,

So wether it was the spark plug on #2 cyl or the spark plug coil or running the mix with lukas magix fuel treatment. The trouble has cleared.

So praise the Lord and pass the ammunition for the next adventure in H3 land...

 

Awesome.

 

No misfires with clean valves.
