haha... ok, first off i am trying to hook up my A/F gauge...
well my car was running and i unpluged the O2 sensor and no check engine light, and nothing happened. i even let it run like that for a while. and no change. then plug it back in, and nothing happened.
does that mean its broken???

see i have the A/F gauge hooked up, and it lights up, and when you 1st turn on the car the lights move, but then it just stops. and only the bottom green light stays there, and it does not move. even when i gas it... anyone got any ideas?

thank you guys [and girls]

 

I'm not too sure about the A/F gauge hook up, but the O2 sensor......

You will not get a code right away when you disconnect the O2 sensor, it's just the way it is I guess, when mine was not working, it would go a day or two without a code.

If it has never flashed a code before, odds are it's working just fine.

 

cool thanx for the info. a great help. i didnt think mine was broken
