: Runnin without o2 fuses in

I've been driven my car 96 devile without the 02 sen. She seems to run better but was wondering about if any damage I might cause

I am sure that the PCM wil substitute a default value to keep the car running, but it may not be the optimum value. One thought that comes to mind it possible damage to the CAT if you are running to rich.

Are you driving without an oxygen sensor, or without the oxygen sensor's fuses? The fuses don't make much difference... They heat up the o2 quickly so the computer can enter closed loop shortly after startup. At worst you'll get worse gas mileage. Once they're warmed up, they'll act normally.
