That sounds like a major vacuum leak or a bad ISC motor, try putting car in nuetral and set the park brake, start the engine and let the idle stabilize, an engine at operational temp is advisable, then step on the brakes like you are doing a regular stop and see if the RPM's start to climb, if they do then you have a bad brake booster, if it doesn't then it's time to have some shop of your choosing run a "live data" scan on the vehicle, tell them how to,get it to the idle flare up so the tech can watch the sensors and the readout from the ECM, when it's acting up.

Something may be jammed in the throttle linkage causing it to be stuck wide open,
