P0304 fault code
I'm new to the Evo X ownership, not had the car long and as I drove it home from picking it up it decided to throw this code and run on 3 cylinders first thing I checked was plugs and the plug in cylinder 4 was broken a very small part of the end had come off so I replaced them all think this was the fault but even after changing them all it still not running on cylinder 4 I've checked the plug and its sparking I've swapped 3 and 4 injectors I've checked there is power to injector and still not running cylinder 4 it's not overheating it's not smoking I'm going to check the compression I've just ordered the kit but what else should I check ??

I'd do a leak down test also.
If a piece of the old plug was missing. There is o ly 1 place it could go....
