I've been having this problem where it wants to lope and jerk at idle and while rolling at idle, but it seems to run fine the rest of the time. I ran codes and got a code sayingthat "intake air temp. is higher or lower than expected" and "lacked of heated air indicates lean condition bank 1". The DCL scan also showed the O2 sensors as reading invalid.
So, I clean the IAT sensor out and run codes again. This time it gives, 314 Air system inoperative in KOER bank 2, 311 Air inoperative bank 1, along with the typical 332 EGR flow insufficient. These are always there and give no problems. The odd part is that it still says that the O2's are invalid but there are no codes being thrown for them.
This is driving me NUTS!!!!
