Still in process of locating the misfire, so I finally found the ohm meter and measured each wire.
Came up with these numbers in resistances (longest wire to shortest):
3900
3500
3000
2500
These are on some year old (7k miles) NGK wires. I tried searching for normal resistance numbers, checked the manual, but haven't found anything.
What number range should I be looking at?

^ I think those are higher than stock to be honest.
Do a search for something like "wire resistance" by a member called "rallyman". He tested his & I'm sure his used stockers had a lower resistance than your NGKs.

Here's the link to my original post in case anyone wants to see it.

Enigo, your NGK wires seem to be slightly lower resistance than mine were when they were new.
As an update, I now have Bosch spark plug wires installed on my Tib and they tested the lowest resistance of the three. I can post the actual numbers if anyone cares to see them.

I think someone posted the PRD resistance values on the site somewhere but I have never owned them so I can't comment. I'll summarize my results below.
NGK = 5.6/4.4/3.7/3.0
OEM = 3.1/2.5/2.1/1.6
Bosch = 1.14/0.89/0.77/0.6
All values are in K Ohm.

^Agreed on the NGK's but my Bosch wires are virtually identical to the PRD's in resistance, are gauranteed for life and cost me about 1/3 of what PRD's would have cost. Granted they don't have the "pretty" factor and I got a great deal from a seller on Ebay but I'm happy with them so far. If I never have to pay to replace the plug wires again then it was money well spent.
