Check the wiring to the coil. Make sure it's not broken somewhere. Also make sure the terminals in the plug itself are ok. An injector may cause that misfire also. Too bad it can't be one of the easier cylinders. Those #4 and #8 are a pain.

9/26/06 Never heard of that but I do know for a fact that year and motor had a problem with the head and gaskets letting coolant into cylinder wall causing misfire could also be seizing your plug and breaking during removal hope this helps you

Why does cylinder 4 always misfire on a 1998 F150?
Need more information (such as engine size) to tell you why. Experience is anyone of them can misfire but Fords of that vintage sometimes have problems with cooling leaks on that hole from heater hose I had exact same problem on my '99. Leak on #4 plug caused damage to the coil. Changed hose and coil. Coil very easy to replace. My brothers 98 F150 had the same problem, had to change the intake gaskets. All four corners of the intake was leaking. Took about 4 hours to repair. His was a 4.6 motor.
