Since the system seems to respond to created O2 signals, one might suspect the real signal, but lets test it. Hook your volt meter to the O2 sensor lead (leave it disconnected from the controller). If you get 1v the system is rich (or the sensor is lieing). Use the 12v thru Cap'n method to lean it out. Does the method make the engine run poorer? Does the voltage drop below 1v?

Lost me here. How can it make the engine run poorer if it's disconnected? I am testing a disconnected o2 sensor on the sensor side for both tests, right? Would the engine even need to be running for this test?
