MISSING

2000 Cadillac DTS

Engine Performance problem
2000 Cadillac DTS V8 Front Wheel Drive Automatic

I used an OBDII scanner and got a code P0304 cylinder 4 misfire, I have changed the boot and the plug, perhaps you can give me more info towards repairing the problem.


Thanks in advance for any help you can give me.

Swap ignition coils side to side and see if the misfire goes to cylinder #3.
