I have a 2000 lincoln navigator and my engine is misfiring. Autozone scanned the CEL and got back P0304 (misfiring on #4). I have had the #4 coil changed twice along with a new spark plug and it still continues to misfire. What else could it be.
have the same problem?

Check the spark plug, compression and fuel injector on #4 cylinder.
