well besides bigblue's adjusting...i have come across a better way to reset apps than disconnecting the batts and waiting over half an hour...with the batts hooked up, turn the key to ON, then depress the skinny pedal for longer than 10 seconds and less than 15...then release, and do it once more...then immediately fire up the truck never turning the key off...i have found this procedure much more effective, especially for my erratic apps problems, and this you can do this at a gas station, or on the side of the road.
