Hello Steve , congratulations for driving such a fancy car. I will try to help. My first guess would be to check in the area of the cruise control for vacuum leaks. There are hoses that come from your engine to the cruise control that in some way make it work. Get a piece of 1/4 inch rubber hose and use this as a listening devise , one end to your ear and use the other to listen around the the various hoses. Possibly you may find broken, collapsed, or cracked hoses in this area. Check these things first and please get back to me, GOOD LUCK.
