Engine Revs up on its own, ESP.

Here is a hard one. So on start up the engine revs up on its own real high, or it loops from 1500rpm back down to 500rmp on and on, if I as much as touch the accelerator pedal it then starts revving up on its own. So the check engine light was on for a day or so prior, then when driving after start up the ESP code was displayed. Does anyone know what this could be, cat sensor, mass air flow, low battery/ alternator, or anything else? 2002 C32 amg
