1998 ford ranger number four spark plug misfiring. code P0304

I have a reacquiring miss firing problem with my 1998 4.0 Ranger. Is there some problem that may be causing this? OBD II code reads P0304 number four spark plug miss firing. I will just clean or remove and replace the plug, but I would like to know of a possible cause, so I can have the problem fixed. This has reoccurred three times since I have owned this truck at about the same mileage gaps I replaced all of the plugs and installed a new coil pack 8559 miles ago. Thanks for any suggestions with this problem. Thanks for any help with this problem.

Go to a local Napa, or Shucks automotive store and ask for the computer to plug into your vehicle and have it give you codes. Take those codes to the employee at which ever automotive store you went to and he'll tell you what issues you have.

This would be the forth cylinder from the front(where the pulleys,and belts are).There will be a coil,and under the coil,is a boot,connected to the spark plug.The miss fire could be any,of the three.I would replace the spark plugs (all four)and the boots.Then if the miss fire is still there,replace the coil,on number four cylinder.

Missing problem


Check the wire pigtail that plugs into the coil pack. The plastic insulation around the four wires become hard and brittle, this can cause shorting and cross fires. Carefully pull the protective cover back to expose the four wires that go into the plug, check visually then bent the wires to see if they are flexible. If they are flexible and not brittle it is something else. Check out this link for detailed information and tests.
