There is no way to test and IAC and know it will be trouble free. Just because it checks out electrically doesn't mean it will respond quickly and accurately.
How did you check for vacuum leaks?

Start out by cleaning the throttle body thoroughly but you may have to change the IAC.

I checked the vacuum with a smoke machine

Yes, that's the best way.

A little unclear - "dies when ever you stop"
Does it only stall in D ? It will idle ok till D selected?
will it stall in N - try shifting to N as you slow to stop? Might be a TCC issue.
Scan for codes even if light is off - post all codes.

The car may have an overdrive switch or selector that can be shut off to test that theory.
