What you're describing is simply an idle speed that's too low. The symptoms are you need to hold the accelerator down 1/4" for the engine to start, you don't get the nice idle flare-up to 1500 rpm at start-up, and it will tend to stall at stop signs. Most of the time that is the result of the Engine Computer losing its memory because the battery was recently disconnected or run dead. Often there is a set of conditions that must be met to trigger the relearn to take place. I only know that for Chrysler and Mitsubishi products you must drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals. Other brands have their own set of conditions, and many will do the relearn without you doing anything. Before you look for difficult or expensive stuff, I would stop in at the dealership and ask one of the mechanics if there is a certain procedure. I would not talk with the service writers because most of them never were mechanics, and there is a good chance they won't know if there is a procedure or what it is if there is one.
