Re: Something wearing out on a 300?

Good quality plug wires like this should check on an ohm meter around 800 ohms, so get a multimeter and eliminate a dead wire as a culprit. Also, make sure a plug wire hasn't gotten a bare spot rubbed or worn into it from engine vibration against a valve cover or sharp corner somewhere.
