Nearly stalls on warm start (video) . . . going to get worse?

Nearly stalls on warm start (video) . . . going to get worse?
Hey all,
2007 G35x with 66k miles on it. I've kept up with the regular maintenance intervals.
A few weeks ago, I was having a strange issue where my RPMs would hesitate around 1100rpms from a cold start. I solicited suggestions on here and, after searching around, people suggested the "easy" fix to try was the ECU upgrade. So I took it to the dealer and had the ECU upgraded on 10/14/14. I also had a radiator hose replaced.
The ECU upgrade appears to have fixed the issue--I haven't noticed it since.
However . . .
I've been driving it for about a week straight, and I've noticed a new problem. When I try to start it on a "warm start," it does this:

When the RPMs dip that low right at start, the car shutters just a bit (as if it is going to stall). It has not stalled yet, however. I would anticipate that this is just going to keep getting worse?
I searched around on the forums, and some have suggested this might be related to a dirty throttle body or perhaps a mass airflow sensor issue? Some also mentioned camshaft position sensors.
Anyway, the dealer is about 90 minutes away. I'm looking for a complete list of things I can clean / replace myself (or that you think the Nissan dealer is competent to do, since there IS one of those locally) . . . before I limp back to the dealer. This is getting frustrating.
Thanks for any help!

Mine does it too, but more like at idle such as at a stop light or even at a shirt stop sign stop, not necessarily on start. Cleaning the tb helps a little, but doesn't fix it. Sub'd for a solution, but as far as I understand its just something we gotta live with.
Of course mine hasn't ALWAYS done it, so there must be something to fix it.

Mine has been doing this really since I modified my exhaust. Maybe it did it before but I didn't notice. At at a red light the car sometimes fluctuates rpms too, going from 600 idle down to 500 and back up. I've never cleaned the TBs or had anything done at a dealer. Btw, my car is used with 83k on the clock.
