Some cars do that when they have a miss to them? You can sit there and watch the rpms drop and come back up driving or at idle, idk if thats what yours is doing but just a sugestion

Could possibly be the idle air control valve. Also if you have a light on bring it to a shop and have them run it that could tell you what your problem is.( and I'm suprised no one mention to do that yet, when I have a light on and the car is acting up first thing I do is check the light)

At autozone it's free, if you take it to a shop they may charge you a 50$ diagnostic fee also if you know someone with a handheld tuner you can check it that way also
