This sounds like a dangerous situation. it is most likely your idle air control device. There should be a Check Engine Light/Service Engine Soon Light on, yes? Have your car scanned and the problem traced down. You could kill yourself and/or some one else!! Be careful!!! I recommended that you have your car SCANNED first.
