What kind of plug wires are you guys running?; I put on new Densos to solve a misfire, and they still arc?

So I have had this pesky misfire at idle in my 1.0 for quite a while. It is just a shitty miss that drives me crazy. Recently, the car has been giving me a P0301 code (cylinder 1 misfire).

I also had a hard time reading the timing with my timing light. When I pointed the timing light at the pulley it would show the cylinder firing, but the timing mark just WASN'T THERE! I finally traced the problems reading the timing and the misfire to the spark plug wires. When I separated the wires off of the holders and far away from each other I could read the timing just fine, though it still missed. But with the wires on the holders, the timing light was all over the place, it misfired like crazy, and my timing mark could only be seen steadily from UNDER THE CAR on the bottom of the pulley. They were arcing that bad!

I had crappy $20 Autozone wires on it, so I put on "OEM" Denso wires from Ebay. Still has the arcing. When running the engine in a dark room I can spray water on the wires and the light show it produces looks like something you would see at an Ozzy Osbourne concert. I can actually HEAR them arcing and sizzling. I even swapped some original 14-year-old Sumitomo wires from my girlfriend's '99 onto my car to see if the new wires were the problem. Still does it.

Do I need some kind of "super wire"?

What else could cause this with THREE sets of wires?

Is there something not grounded properly?

Plugs are gapped right...changed the dizzy...and the ECM...everything looks good?

Thoughts? :hmm :hmm :hmm :hmm

Three sets of wires? Sounds to me it is NOT the plug wires. Start looking for something else. Coil, Dizzy, bad ground........

I would first look at the grounds. Simple and easy to trace the grounds laying around the engine bay. Pull everyone off and brighten them up. Remember, bad grounds in our metros make odd things happen. You just might have one of these odd things happening.
