I think that your car's trying to tell you that something's wrong with it so it might be a good time to get it checked out!

FAST IDLE VALVE!!
This valve controls your car's idle according to the coolant temp when your car is cold. Basically if the coolant is cold it allows more air thru, uppin your idle. It has only hoses going to it, no wires, it's purely mechanical.
As for up and down when warm, it could also be because your fast idle valve is really bad as in stuck open or seized, or your BISS screw on the throttle body is not adjusted properly.
Or you have an vac leak, but that's less likely to cause such a noticable problem.
