Code P0140 O2 sensor I have replaced my o2 sensor 3 times already and this code keeps coming after the first 20-50 miles after I replaced it. Is there anything else I could do? I had the car tuned again as well. Any help would be great.
Thanks

I think the answer to my question this code is for the rear o2 on the driver's side. Autozone told me it was before the cat which is wrong. Correct? I thought the rears were tuned out, but maybe the driver's side was forgot about.
