Mark: Please allow me to plead stupidity on this issue. I stated that your gauge appeared to be working backward. I appologize for that statement. I sat and thought about it, and admitedly, it has been awhile since I had to diag emission problems on cars. But your gauge is reading correctly, if memory serves me correctly.
The sensor reacts to oxygen in the exhaust and not fuel, so any motor problem that allows unburned AIR to pass through the cylinders will also trick an O2 sensor into reading lean. A misfiring spark plug or a leaky exhaust valve, or even a leak in the exhaust manifold gasket will allow enough air into the exhaust to screw up the sensor readings.
