Is this a problem? What to do? Engine revs slightly on its own while idling













Hook up a scan tool capable of live data and look at fuel trims. If your A/C is on, turn it off and see if that makes a difference. If it does then if you haven't cleaned & lubed, or replaced your IAC valve in a while, I'd try cleaning it.
