[ftwaynebullitt]

4 years ago I got an off road x pipe for my 01 Bullitt. I got the Eliminators so the Service Engine Soon light would not come on. I have never had any problems until a couple days ago. SES light came on. I went to Autozone and they said it was the O2 sensor, bank 2 position 2, is that the front or rear O2 sensor? Also, if it's the rear sensor, could the Eliminator be malfunctioning? Or do they go bad over time and does it need replaced?:?:

Any help would be appreciated:worship
