A vacuum leak can do that. Check the gasket at the base of the throttle body for leaks. It was common for that gasket to crack and allow a vacuum leak. With the engine running, spray carb cleaner around the base of the throttle body. If the idle changes briefly while you are spraying that area you have found the leak.
