Honestly it look very new already do think that would cause the issue I’m having. I can let my car run for 30 minutes. Turn it off and when I crank it cranks for like a second or two and dies cut off on me at the traffic light the other day very frightening had to push it out the way don’t want to keep throwing parts at it

Try banging on the IAC with a piece of wood. If the idle improves you need a new IAC.
