Then the car will idle like crap

Why have it on if you don't have an o2 sensor? It's pointless.....and will make the car idle and possibly cruise bad.

Just pull it out has the same effect as disabling it.

The PFC/FD does not use the O2 sensor for idle.

yes blazin.......thanks.............of course it its pointless to leave it enabled if it is unhooked.....just curious to what the car would do......

Newbern..........u mean just disconnecting the o2 sensor from the wiring harness will disable it on the pfc???

It's kind of pointless but yes, if you disconnect the o2 sensor the PFC will simply not use the input. Same result as disabling it via the commander.
