Mine does this too a bit, although it is erratic. It feels like, as you say, a marginally low idle. I have the climate control on mine and the kids fiddle with the rear controls all the time, so it's hard to correlate, but I think it is just the extra load from the system cycling on and off. It does sometimes go away on its own while at a stop light and other times the idle will dip while stationary for no other reason I can think of.
