Expert:  Lil Hammer replied 6 years ago.
First thing to do is remove the air tube that is attached to the throttle body. Look inside at the throttle plate it should be vertical. If it is not and is partially open something is causing it to be open such as a foreign object or throttle linkage. If the throttle plate is vertical and not stuck open then it is likely that your idle air control motor is stuck, replacement would be recommended.
