when I unplug it nothing happens, if I ground it, the current goes to
+-20mA, which the Bentley says means the ECU is OK.
I swapped the DPR, Knock box, airbox, ECU and lastly the O2 sensor
w/spares I have and no change.
I imagine the O2 sensor needs a ground. Has anyone ever heard of
grounding problems with the O2 sensor?
I'll pull the sensor and check my soldering....
the O2 sensor wire is shielded. I remember something in the Bentley
about where the shield is grounded but can't find it now. Could a bad
shield have anything to do with it?
thanks again,
Steve

Subject: [a2-16v-list] OXS problem??
Ongoing (year+) hesitating/misfire under load. Did all the tests in
the Bentley (again). DPR current 10.3mA no fluctuation. New O2
sensor, and I even tried putting the old one back. Before I buy a 3rd
sensor, I wanted to double check. How is the O2 sensor ground?
Through the pipe/manifold? Any chance that grounding might be the
problem?
thanks,
Steve
