IDLE Misfire Help

[Jaded S4]

Hey Guys,

So I'm getting a bad misfire while the car is idle. It runs fine otherwise. Here are the DTCs that came up:

16534 - Oxygen (Lambda) Sensor B2 S1: Malfunction in Circuit
P0150 - 35-10 - - - Intermittent
17539 - Oxygen (Lambda) Sensor: B2 S1: Internal Resistance too High
P1131 - 35-00 - -
17538 - Fuel Trim: Bank 2 (Mult): System too Lean
P1130 - 35-00 - -
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16690 - Cylinder 6 Misfire Detected
P0306 - 35-00 - -
16689 - Cylinder 5 Misfire Detected
P0305 - 35-00 - -
16688 - Cylinder 4 Misfire Detected
P0304 - 35-00 - -

So far I've tried to change the spark plugs, swap ICMs and move coil packs around. Doesn't seem to be any of those. I'm kinda stumped at the moment. Any idea's or input?

Thanks in advance.

o2 sensor, bank 2 (driver), s1(pre-cat), swap it out and see if that helps

Would an o2 cause a whole bank to misfire?

yup, especially when the O2 sensor that your car is telling you is bad is also the one that controls that particular bank...
