I have 05 Excursion w/Edge-Juice programmer, AEM intake and Banks exhaust....other than that it's bone stock. Any insight & guidance would be appreciated!!!

First thing I would do is remove the Edge, check your CAC hoses for leaks, clear the codes and see if it comes back.

That is a common place for them to split, It should clear up your issue.

Side note; the Edge juice has not been noted for being very good for the Torque-shift tranny.

Make sure you clean everything with brake cleaner to get rid of any oil film. Then take some hair spray and spray a "light mist" on the tube and the hose before you put them back together. Should keep you from having the or a big bang under the hood as you step on it getting on the freeway or going up a hill.

You have the situation under control.

In my case, the issue was a badly plugged EGR.
