What are the signs that you need new spark plug wires?

Some of my wires are mushy and my tail pipe is making a little pop, pop, noise at full throttle. I already twisted the distributor back and forth but it still does it.

I have 2 day old spark plugs but the wires are old

thanks

Start the engine at night and look at the engine, sometimes you can see the spark leaving the wires if they are bad. The other way which I usually use if no spark is visible is use an ohmmeter on the wires to check for continuity and ohm value.

I'd replace the wires, anytime wires are "mushy" I question how much spark energy is being lost. They are cheap enough....

Did you gap the plugs?

Once this is checked out, get the timing light out and set the dist timing again if you moved it around. Good Luck

if u replace them u may want to consider using stranded wire instead of the carbon type... but if u have a radio stay with carbon..

the wires were the cause, thanks everyone
