P1504 Intake Air Control circuit malfunction.
P1506 Idle Air Control Over Speed Error.

I wonder if your IAC went bad. I would google the codes and see if it has any solutions on there, I dont know enough technical stuff but thats what the codes are.

Yep I pulled and looked up what they meant, but don't know where the IAC is.... we just swapped the eaton back onto my truck and if I'm right the IAC is the silver round tube on the passenger side on the plenum...? Or is it the black valve tha opens and closes on the drivers side in the rear?
