OK what is ht lead? Kohm equals 1000 ohms of resistance in the part or wire, so whatever the resistance is is large, but for what lead?

Heli-Core Wires (Blue): 150 - 1,200 ohms per foot 8.5mm Super Conductor (Red): 40 - 50 ohms per foot If you do not know the specification for your wires, measure the resistance of each wire. Remember to divide the length of the wire by 12 to get a "per foot" measurement. If one wire is out of that average spec, it is at fault Solid Core Wires: You cannot run Solid Core Spark Plug Wires with an MSD Ignition Control. Solid Core wires do not suppress any Electro Magnetic Interference (EMI) which will interfere with electronics or rev limiters on your vehicle. A suppression style or spiral wound spark plug wire MUST be used.

On your vehicle there are two spark plugs per cylinder. One coil pack per cylinder with two coils in each pack. Wires are six or eight inches long with a suppressor which connects to the spark plugs. On the suppressor you will see stamped a spec for the resistance through the wire plus suppressor. Usually they are 1 K ohms. If one of the wires is unusually high (1.5 K ohms or greater) I would replace it. Try to determine which cylinder is misfiring before testing every wire.
