Eric, my man, the leads from the O2 sensor are within a black wiring LOOM 
(i.e., jacket, sorta).  At the ends of the leads you will find the 
connections to the wiring harness.  The connectors are two in number, one a 
two-terminal connector for the power to the O2 sensor, the other a single 
terminal which is connected to, guess what?  A SHIELDED single conductor with 
a thick, STIFF, BRIGHT GREEN outer jacket (unless some jabonie before you has 
exchanged it for microphone wire).  As I said before, the SHIELDING on this 
signal level conductor can wear through the insulation of the inner conductor 
at the terminus of the wire.  This will effectively ground out the OXS input 
to the ECU and the symptoms which you described will exist.  Now, go out and 
play.
