Poor peformance, question why do you want run without it, kinda hard to understand what your asking. Thanks.

i ask this b.c autozone gave me the wrong o2 sensor and i had went back and replaced it but i dont get the o2 sensor untill tomorrow and i needed to get the car home from the shop so i had no choice but to drive it with out one. but i didnt want to wait till tomorrow to find out. the car kept bucking and it ran like crap and wouldnt hold idle kept stalling, i have a CEL for IAC also

The car won't run right at all because the ECU will have nothing to reference to properly set fuel trims. It will basically run like complete crap. I would recommend not driving it until you get the new sensor.

Did you just plug the hole or what?

+3, if it was me i would have just popped the old one in until i get the new one

First, you will get a CEL... and since the ECU detects no signal from the front 02 sensor, it will try to run the car in "limp mode" which is basically a extremely rich A/F mixture...

I wouldn't drive the car like that more than two or three blocks, I rather wait for the new sensor to arrive...
