Its not an O2 sensor, that would be the exhaust heat sensor, it trips the 'Exhaust Overheat' light on the dash. You dont really need it.

psh you aint hip

sooo should i cut it? or would it turn the light on in the dash? how should i go about removing it?

I would image just cutting the wire would do ... i'm getting my exhaust done on monday and i think that i'll try to put it at first ... does anyone know at what temperature does the sensor trigger the light at?

On the 84/85 12A cars, there are two exhaust temp sensors. There is one in the floor board like the other 1st gens for the exhaust overheat light. The one he is talking about is a thermoswitch in the exhaust itself. This is only on the 84/85 12A cars. It is used for the emissions system. I believe it is used to control the ACV. You should be able to just unplug it without any issues.

ok thanks alot if i cant unplug it can i snip it?

Yeah, as long as it is a one-wire senor, which I believe it should be.
