Hello, Heres the deal. I'm still trying to find out why my project car is running rough. I've swapped out the coil & checked (and rechecked) the plug wires

are installed correctly. I have a new set of Magnecor wires on it and a new set of NGK iridium tipped plugs as well so I thought about checking the wire

resistance. I've been told that there's an acceptable range for this. I looked through both the Bentley and the Haynes manuals and I can't find this spec

anywhere. Does anyone know what the resistance is supposed to be? Here are the readings I have. They are (reading from front to back looking down the engine

block)#1)4.30 ohms, #2)4.44 ohms, #3)5.17 ohms, #4) 5.01 ohms. Are these okay? Thanks, Charles (BTW, I also have a new Bosch cap, rotor and hall sensor

installed too.)

    Basically your wires don't have much resistance. Ie. plug resistances are usually measured in kilo ohms.

    Measure total resistance. Ign coil cable + spark cable + plug resistance. I think it is recommended to keep it under 12k ohms. Different set-ups require/use different resistances. Even ignition coils have different resistances. If on acceleration up a slope there is hesitation/misfire then your total resistances may be too high.

    (Mine is around 8K ohms but I've got a points system converted to electronic ignition)

    Plug wire resistance values are OK (nmi) 200
