1995 MAXIMA, OXYGEN SENSOR QUESTION HELP!

[Jose95MAX]

Well recently the check engine light wen On and got it checked out, they told me the Oxygen sensor was out and had to replace both, i checked my engine today and 2 sensors where disconnected one by the radiator and on in the left back corner...i was wondering are those the OXY sensors??? and if its bad to drive with them disconnected, and why would they leave them disconnected?????????/

Yes those would be the O2 sensors. I have no idea why someone would leave them unplugged. When the sensors go bad, the computer goes to a default setting that will probably make you run rich (which could affect mileage).

Yes.
