Engine Idle and Stalling Problem

[Bulldoggie]

I had same symptoms a while back.
Mine was the Idle Air Solenoid.
You can remove it and clean the inside with brake cleaner and a small wire brush.

I found the large hose clamp has loosened on mine more than once.
The big one on the intake tube in the lower corner of the red box outlined in this picture.
I've replaced my Fuel regulator, TPS, and cleaned the IAC solenoid, all the cheaper stuff, but my problem still plagues me. One of these should cause a problem every time and not just once in a while?
I'm thinking of having a smoke test, to look for a Vacuum leak, AND buying a "test" or used MAF. I have finally had some codes other than low flow EGR.
I've had lean fuel on both banks. It's probably the MAF, but at $450. I might have to wait for a Tax return
