The idle while running in neutral while driving (at stoplights) is also normal. It's just that very first cold start that does the strange stumble-->dip-->rev up--> then normal idle from that point on. This happens like clockwork when the car sits for about 24 hours.
Mine acted just like that, and then got worse and worse and started doing it all the time.
