Ok, I searched the forums and can't find any specific reference to these codes, so here goes. My car starts fine and idles cold but when it reaches operating temp, it has a wandering idle, will idle down to the point of stalling and will only restart at WOT. The code scanner gives me KOEO codes 81, 82 and 84 and Continuous memory codes 14 and 33. The 33 and 84 codes I understand; I have an EGR eliminator plate. Fordfuelinjection.com lists the 81 and 82 as Air management 2 and Air management 1 circuit failure, respectively. Is this code referring to the IAC valve? The IAC is only 6 months old and I tried cleaning it Sunday, however, it was an Autozone part and I've never had good luck with any of their engine management products. The CM code 14 is the real confusing one, 2 or more sucessive PIP pulses? Any one know what that means? I'm going to try cleaning the IAC again and if that doesn't help, I'll replace it with a NAPA or FoMoCo part. Another thought; my TB did have an Idle Air Bypass Plate before, but I swapped someone TB's to help with hood clearance issues on their car and when I got my TB back, the bypass plate and IAC were gone. The car ran fine without the plate for a few months, but now I wonder if I need another one. Any pointers are appreciated.

81 - Secondary Air Diverter Circuit Failure

82 - Secondary Air Bypass Circuit Failure

these refer to your secondary air injection system. otherwise lovingly reffered to as "the smog ****"

Ok, I can ignore those codes then...smog pump is next to the EGR stuff in the attic. Guess I'll try another IAC valve to see if the Autozone special is crapping out when it warms up.
