This is a discussion on o2 sensors within the General Help forums, part of the LSx Technical Help Section category; I went to autozone and they said both front 02 senors were bad. I just replaced the bank 2 sensor ...

I went to autozone and they said both front 02 senors were bad. I just replaced the bank 2 sensor 1 yesterday....(the thread was stripped and it wouldn't thread all the way in) but it seemed to be working fine. I have never replaced bank 1 sensor 1... I was wondering what would cause it to go out so quickly(it was a bosch o2 sensor) it was running pretty rich before I deleted the rear o2's would that cause the front o2's to go bad?

If its leaking from the bung or befor the sensor then it will throw a code.
If you have headers its a possiblity, i ran my old 02's for about 20 miles and both of them fouled out because of the ceramic flaking off, replaced them and was good to go.

I replaced both o2 sensors and the car still bogs down when you accelerate hard but if you roll into the throttle it doesn't bog down! any ideas? its doesn't seem to be throwing any codes either?

could it be the mass airflow sensor? I removed the screen.

See if any codes come back after a few ignition/drive cycles. What were the original codes when auto zone said both front sensors were bad? Great free service they provide reading codes but can't always trust the person reading them knows what's going on - both precat sensors throwing codes at the same time could be a symptom of something else going on - dirty MAF, vacuum leak, etc.

I changed the fuel filter and it ran great for 3 hours or so I was able to open it up at any rpm range... then it started doing the bogging shit and the ses light is back on. sounds like trash in the fuel tank? could it be anything else?

Did you have the cats checked? I had a cat go out and it must have caused the o2 sensor to go bad too. The cat got changed under manufacture warrenty because there was a recal or something but the sensor was bad also.
