I've been occasionally getting a cyclinder #1 mis-fire on my Stang, and I'm guessing it's because it still has the original spark plug wires after 10 years and 160K miles. I did replace the plugs about a year ago, so I'm guessing they are fine. What I was wondering is....how easy or hard is it to replace the spark plug wires on a '99 V6? Any help is appreciated.

 

I think it's a piece of cake. Layout your new wires by length and replace them one at a time.

i have a 2001 i had the same problem i replaced the spark plugs and the wires look fine what else could it be??

 

Once I replaced the wires.....issues is gone. I thought that was probably the case, glad to have my '99 back to running the way it should.
