Did you clean the idle air system? Shouldn't be any egr flow at idle. Any applicable mil codes. You use a jumper wire between A & B terminals @ datalink connector. Turn the key just till dash lites come on, no further, the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

I'm just killing time, sounds like you found your problem. Have a good day.
