Look at the output on a voltmeter. Voltage out shows lean, normal or rich condition.

I havent ran it yet after taking it off. I havent put the new exhaust on yet. The power wire (red wire) was running to nothing...and the O2 sensor wire wasn't running to anything, either (unless i accidentally unhooked something). Ill be sure to let you know. Im happy i dont need it.
