Hi George.  My O2 sensor has 3 wires (two white, one black) covered by a
black shield, so I can�t figure out where the bright green conductor is
that you refer to.  I must be missing something...  Do you have an older
Vanagon with the single wire OXS?  Regardless, the insulation on the
wires off the OXS look intact, and I have run the engine with the OXS
disconnected - there was no improvement.
