idle at start up 900

Hello to all and thanks to those of you who responded to my past questions. I'm a little bit confused/concerned. When I start up my car (940 turbo) when it is cold the idle goes up to about 1200rpm and within 20secs or less the idle drops to somewhere between 7-900. When the car is warm at start up the car idles around 1000-1200rpm. I was wondering if anyone could tell me what might be going on here. I know that at cold start up idle should be higher for longer. I don't know if this would make a difference but I had a bad inter cooler hose which I repaired and I suspect a minor vacuum leak in the hvac system. Any info/ideas on what is going on here would be helpful.
Thanks in advance!
