CQ Plug wires



I spent part of my Saturday installing new Magnecor plug wires. 
The 8.5 mm Magnecor wires went in without a hitch, except for 
the plastic cable guide that routes the plug wires and injector 
wires cracked in about 75 different places, spewing little pieces 
of plastic all over the engine compartment. No biggie; it still 
stays together - it's just got better airflow through it now.

The thing that bugs me is the resistances of the wires. The 
original wires I took out were all within spec (4800 - 7200 ohms, 
I think), but they were _old_ -- I've observed the spark jumping to 
the intake runners. Most of the new wires were below spec. The 
coil wire was fine, but the shorter wires had low resistances. The 
resistance of each wire was predictably higher than the previous 
(shorter) one, until I got to the last two, which were both just 
above 4800. The car runs fine with them, but I wonder if the 
discrepancies between cylinders will cause problems. Also, what 
problems would a low resistance wire cause?
