Ok i just got my car out of the body shop from an accident. It was there for about 2 months. The car is perfect but now its running like crap. I plugged in my scanner and it is reading a bad 02. bank 2 sensor 1. But I thought it was that a couple months ago and it ended up being my spark plugs. The car is bogging down and tasking forever to shift a4. Does anyone have advice Because im so low on cash. I hope its a quick fix thanks

 

You could swap sensors and see if the code follows the sensor. If it does then the sensor is bad. If the code stays B2S1 then it's the wiring.

 

Can we get an actual code, and not a vague code description?

 

Some information about the car would also be helpful.
