the guys at autozone said my rear 02 sensor was dead after they checked the ecu, and i dint change it for about 3 mos, and yesterday my celjust turned off? i know the 02 sensor still has to be changed but is some thing else wrong? why did it just shut off?

 

thats strange. . . very strange. I'm sure it will come back give it enough time.

How come you waited 3 months to change the o2?

 

it ddint seem to effect gas mileage too much and i heard that sensor dosent affect performance so it wasnt at the top of my to do list
