It's not a magic wire.  What does this $100 cdn get you?  I believe the
co-axial part is just shielding to prevent interference from the ECU.
Check the wire at the ECU connection and verify the its integrity to the O2
sensor.  Wiggle it around to see if it is broken internally.  Look for worn
through insulation.

Subject:  O2/ECU Coaxial wire...

after all the discussion with poor idle and faulty O2 sensors etc in the
last couple days I too replaced my O2 sensor and still experience poor idle
and occasional hesitation (usually in wet/humid weather). This leads me to
think I have a short in the wire that runs from the ECU to the O2 (as
someone stated that they are know to short out). Well, I checked with the
dealer on the part number 443 971 108A and they want $100cdn for it. I
would
spend the money if I could guarante this would solve the problem. But after
replacing parts more so out of the  "process of elimination" I'm kind of
hesitant that this will fix the problem.  Is there a way of testing this
green wire to see if it is the culprit???
any advice will be greatly appreciated.
