Is it at idle while accelerating or while cruising? We can't help you out if we don't know the condition and if it does it all the time or just after starting or after warming up etc... etc... Just throw in a little more information and I am sure some one can chime in with help!

mine does this too maybe every couple days or so.
when i start, the idle will be a little jumpy, but it'll stop after i drive for maybe 1/4 mile.
doesn't matter if the engine's cold or warm either.
doesn't bother me that much, but i'm curious as to if it could get worse

have you tried cleaning the throttle body or MAF?

Have youever disconnected the battery?If you did go have your "basic settings" performed.This adjusts your idle.
