Just go out and drive it. If the battery was disconnected or run dead recently, the Engine Computer has to relearn "minimum throttle" before it will know when it has to be in control of idle speed. Until then you also won't get the nice idle flare-up to 1500 rpm when you start it.
To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.
