throttle body is dirty and possible its plugged the idle circuit ports. Also check for dirty air filter and passages while you have them off to do the cleaning. Rev the motor and while spraying throttle body or brake cleaning spray cleaner. If that fails, check operation with OBD2 software (Autoenginuities software/hardware solutions www.autoenginuity.com) to cycle the throttle through its motion and or reset it.
