I was riding around for a few hours tonight, all over the place. It started getting dark and at a stoplight I noticed something - my #3 cylinder's spark plug wire is arcing from the boot to the block. Its only intermitten but the spark is almost an inch long.

So where is the problem? Boot? Plug? Both?

I'm planning on replacing the plugs already.

I wish I had a tad more patience to do it better!

You most likely have a crack in the boot and some exposed bare wire (had something similar in an old truck I used to have). replace the wire and/or boot after inspecting it.
