Thank You MBDOC. Hello MRslico
MBDOC, I was hoping someone authoritive would tell it like it is. Replacing Ignition Wires like you change engine oil? I replaced my original wires at 145,000 miles and 10 years of service.. I keep the rubber insulators lubed with di-electric grease, and I have no problem when I have to remove one.
MRsilico. How do you tell if the spark plug wires need replacing. Except for the obvious failures i.e. broken or shorting to ground, the Resistance of the wire is measured using a volt/ohm meter. The wires have a known resistance per inch of length and any added resistance indicates a failure. Except for the obvious reasons, you probably wouldn't be able to tell if the wire was bad because the failure is so gradual it just slips upon you. Don't be frightened into replacing your wires without thorough testing. Listen to MBDOC.
