don't waste your time. the stock O2 sensor only reads rich or lean.. you need a wideband for your little rice-o-meter to function worth a damn.

 

If you really want to see that much, you can just turn the screw on your ECU clockwise, start the car, and watch your check engine light blink.. when it's on it's lean.. when it's off, it's rich.. or vice versa..

that's all your gauge will tell you as well.

 

Disco time!

 

the wire is black at the o2 sensor. But they are right its not going to tell tou much other than a nice light show.

 

what can i do about a wideband? thanks for the info though
