I would start by checking all vacume hoses for leaks, check for a dirty air filter, and clean the idle air control valve, and clean the throttle body with a stiff toothbrush and carb spray. You'll probably have to have someone hold the throttle wide open for you while you brush all around the inside of the bore of the throttle body. ( engine off of course.) Good luck.
