View Full Version : measuring resistance in spark plug wires

I recently put in new plug wires (Taylor spiro pro) and I was wondering if anybody knows the range of allowable resistance readings for the plug wires in the 3400. I can't see any real signs of wear in my stock wires except for some oxidation at the metal connectors. But I am almost 100% sure these are the original wires and I have 125,000 miles. I changed the plugs last summer (NGK Iridium), and I know I should have done the wires at the same time.

Reason why I am asking all this is because the car has had a hard time starting, rough ideling, and some slight hesitation at WOT; now all seems better.

Here's your spec. 3000 ohms per ft (9686 ohms per meter)
