Anyone know the remedy? Is the # 2 on bank 2 the post cat O2 on driver side?
Also, didn't bring my O-rings home so I'm now getting to put them in and play...figured It was a lean code but no such luck. Thanks Guys

bank 2 is whichever side cyl 2 is (look at your coilpack =P) which I THINK is the driver's side, but can't remember for the life of me.
