High Idle After Highway Running
My truck has been acting a little funny lately. After running on the highway for an extended period of time 30 min or more, the truck seems to go into high idle mode. At every stop after that, the truck idles high.
The problem won't correct itself until I turn the truck off and back on.
Any ideas?

Try the ignition trick and see what codes you are having.......Start there and see what happens. Let us know
