Sounds like a vacuum lead possibly. Do a visual inspection for any cracked old hoses or loose or unattached lines.

I'm not sure on the code # but I know it was the o2 sensor code behind the cat. Hoses seem to be decent enough but I did find the intake hose near the throttle body cracked so I will replace it.
The IAC Valve was hella gunked up so cleaning it with TB Cleaner made it look and perform better and while I was there I also cleaned the TB itself. First inicial startup..... it ran normal but the idle drop was not present anymore so I hope it stays like that for good (the problem was intermittent).
