reving while idle problems

my car has been doing something funny. it starts up just fine and revs at a perfect 1000--1300 on start up. but if i drive for a couple miles and stop it starts revving really low almost a bog sound and then back up and back down a little. lastnight i came to a light and was making a right shifted into second and died out and was on battery and then started up by itself.
and at times it will idle real low and then go up a little. it drives fine. no hesitation when i hit the gas.
