Very rough idle upon cold start S70

Everytime that I crank up the car after it sits for more than 5 or 6 hours the idle is very rough - the car sometimes stalls out without a tap on the gas peddle. After about 3 to 5 seconds of gasping, the engine runs perfectly well. Any ideas as to what the problem might be?

My girlfriend had the problem and it was a leaking injector.

Thanks, I'll get it checked out. How did your girlfriend solve the leaky injector problem?

I'm not his girlfriend but you fix a leaking injector by replacing it, "IF" thats the problem.
