Default Spark Plug Wire Problem

Okay, So my car has been idling rough for the last month or so. I finally opened the hood and took a look at the spark plug wires. 3 of the 4 seemed pretty good, but the wire for #4 had an ash-like stuff inside it and the conductivity was pretty far off from the other three. This will be the second time I've replaced the wires and I have about 97k miles on the car. What could be causing my wires to foul like that? I do have an underdrive pulley on the car, but that's really the only modification I've done to the electrical system.

Akso, I noticed that there was a bit of oil around a couple of the plugs. Is this something that should cause me to panic?

Thanks, Folks

If you haven't done wires it's just corrosion, just use can cause that. Wires are a wear item, I just replaced mine, they aren't that expensive, check out www.subaruwrxparts.com
As for the oil, it might just be anti seize put on them to make sure they don't weld to the heads...
good luck.
