P0305

My 97 f150 5.4L has been missing on one or more cylinders and I can't figure it out. I got the code p0305 which is #5 cylinder misfire. I replaced PCV valve, fuel filter, air filter and spark plug on #5. I tested the coil on 5 and ohms are correct.

Can't figure out what it could be. The truck is missing at all speeds and RPMs and is beginning to drive me crazy. Anyone run into anything like this or have any suggestions?

Welcome to FTE brodyhyde! Replace the COP on that cylinder and you should be good to go. Good luck!

You can try swapping the COP with another cylinder and see if the fault moves.
