Yes the high idle is turned on . As the title states I lost CC and high idle (I think). Truck was sitting for 24+ hours with 15-30 deg temps. I'm almost certain high idle has kicked in before within these temps. Positive however about losing CC (noticed that a few days ago). There is one thing, I recently had autostart installed. But I know for a fact CC worked after the installation. It seems others have lost CC on this forum. Coincidence or computer/electrical connection to the two?

Wherever I go first I want to go armed with knowledge. There seem to be many computer related enomolies with these trucks.

In my experience a good shre of the problems like this happen when someone messes with the wiring. I would go to the auto start people first. The dealer will probably charge you if it was related to the auto start hookup.
