03 Rough Idle, Codes.

[FargoZ71]

Multiple missfires and bank 2 / sensor 1 O2 sensor.

Runs rough at idle, smooth some times, horrid gas milage.

I picked up a service manual finally and I picked up a direct replacement bocsh o2 sensor, I know its passenger side pre cat O2.

Im going to replace the sensor, but if it doesnt cure it any other ideas off the tops of your head?

I would buy a delco o2 sensor. I had to replace brand new bosches before for setting off codes.
