misfire in #6 cylinder on 1993 Ford Ranger

I had my Ranger scanned and it says "There is a misfire in #6 cylinder". Does anybody know what could be causing this? I've checked the wires, plugs, and coil pack.

have you changed any of these parts because a bad wire looks perfectly fine from the outside and could be broken inside, Start with a new wire set and plugs.
