Well, what CAN happen is that the the antiseize or other contaminant
kills the sensor. Another thing I noticed when I went to plug mine in
was the female blade connector from the sensor lead is not snug
(somewhat loose). I suspect this would/could give give erroneous
readings as well. I'm in the same boat as you right now. My mileage
has suffered of late, so at first I disconnected the O2 sensor and my
mileage got WORSE. Now I've replaced the 02 sensor and it doesn't
seem much better than with it disconnected (though with the '93 the
engine check light will come on if you disconnect the sensor.
Thinking of resetting the computer by unplugging the motronic fuse
for a bit and see if that helps.
