Misfire Help
 

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.

replace your oxygen sensors.

Damn, this is so similar to a post on the B5 S4 forum...
