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.
