My head hurts!

If I'm at max. lean correction shouldn't running with 0amps (O2 disconnected) have made the motor quit since it is now running rich, or are we talking very fine calibration, well within the range of smooth running?

Can I check continuity on the 02 sensor or output voltage while running hot as a test of the sensor?

I will probably run out and get a Mustang sensor later and try to straighten this out before I have the dubious pleasure of watching McLaren get spanked tonight.
