Had only happened the last tow days during driving home from work. Cruise set at 61mph and out of no where my kr will start climbing from 0 to 14!!! Only does it until I about cruise control off or tap the gas. Then its 0kr all the way home. Im driving on a level road at 7am in the morning nice cool temp. Car sits for 11 hours before I drive it home from work. Any idea whats happening?
