My cruise was very irratic, I went to the dealer for a reflash (dumb move). Now I only get 10 mpg when towing, and the cruise is still the same. I would like to know if anyone is using a high idler with a auto to help with this, or if anyone has found a cure for this problem? I obviously do not need a high idler in FL, but will do what ever it takes to get my cruise back.
