Does anyone know what the part name is that switches the idle from fast back down to normal idle when the engine gets warm. I'm going to put on a new shut off on the IP pump in the next few days, and while I'm in there I would like to correct this problem. She stopped the two idles on start up awhile back. Now she just cranks with one idle speed. Thanks.
