im not have any problems, the car runs fine. Just as a test i uplugged the 02 sensor (the connecter on the end of the wire) and the car didnt run any different. My dosent have any "check engine" light (its a 83) so i dont even know if it would give me one. I guess i'll have to pull codes from it.

If the O2 is disconnected, the car will still run, but will likely run rich. It may run a little rough every now and then, but it shouldnt die. If EEC doesnt see an O2 output, it just reverts to a fixed fuel map. If you had a CEL, it would be on with the O2 disconnected after the motor warmed up.
