My check engine light came on so I had the code checked it indicated that O2 sensors needed replaced then the code indicated a cylinder 4 misfire? ihave replaced the ignition coil pack, checked cylinder compression, changed spark plugs and fuel injector and I still have the po304 code engine misfire cylinder #4??? I am so frustrated what else could I be missing to clear this code issue?.
