Yea, while i was testing out my a/f ratio guage, i noticed that the guage stayed on the last green bar. I know its supposed to jump around a little but it didn't. Im thinkin the oxygen sensor need to be replaced, but i just need to sure. Thanks

I don't know guys, i think im doin something wrong, i hooked everything up right. Hey guys, i don't have the power wires hooked to the car, i just hooked it up to 9v battery and hooked the a/f wire up. Does the positive and negative wires have to be hooked to the car as well or can i just run it to a battery as i did as i wanted to check out the guage.
