You probably have a vacumn leak........one test.......does the cruise work? See attached vacumn line for cruise.....trace the lines back to the top of the engine looking for hoses that are damaged, cracked, or pull off. also sometimes the check valve fall apart. The engine dies because at idle, you are getting too much air.
