Hi Im David. you have an air leak somewhere on the engine. or a vacuum hose came off somewhere. possible from the upper plenum or intake. if you cant visually see it. take a can of throttlebody cleaner and spray it around any vacuum line/hose and around the thottlebody and intake. if the rpms change or the engine sputters you found the area of the leak
