From what I've somewhat deciphered from your horrible descriptions, it sounds to me like you've got a vacuum leak. That'll let more air into the motor than the throttle is metering, and cause it to idle crazy high. Make sure you don't have any vacuum ports on the intake manifold open, and make sure you don't have any broken vacuum lines or hoses. You can take a can of BrakeClean (make sure it's the flammable stuff, they sell non-flammable that will NOT work for this) and spray it all over the intake manifold and top of the motor, and if the BrakeClean hits the spot where you've got a vacuum leak it'll cause the rpm to jump up even higher.
It could be something as simple as an injector not seated all the way, a bad injector seal, loose throttle body, loose MAP sensor, loose IACV...
