Engine wants to stall

Engine wants to stall
I have an LS6 with aftermarket cam (unsure what size), LT Headers in an 02 Z28 vert.
I've replaced the IAC, TPS, MAP, MAF, PCV, plugs and wires.
No error codes.
When coming to a stop sign idle drops way down - sometimes around 200 rpm - then back up to ~900, stays steady, and is ready to go.
No vacuum leak that I can detect. Even sprayed break parts cleaner all around the engine and idle never changed.

First 25 seconds of this video ... that is exactly what my car does as well '99 Camaro Z28 MS3 Cam Idle Electronic Cutout - HD - YouTube
This just the nature of a big cam in these LS1?

Re: Engine wants to stall
Hunting idle like you are talking is usually a tune problem. I had my 403 idling at 825 RPM's pretty steadily with a 236/248 cam. It just needs a little more base idle air and it should be fine.
