2001 Hd 2500 Wont Idle

[[email protected]]

The other day i went to start my truck and noticed that it wouldnt idle and the radio stations had deleted.

I drove the truck for a while and shut if off a few times and restared. Now the truck seems fine. Any ideas?

Yes, mine does the same thing when I disconnect the battery for 35 minutes to reset the computer. Somehow you lost your power connection I would check your battery terminals and ground at the engine for tightness. If I do a major mod on mine I always reset the computer to let it relearn. When I first fire it up it won't idle I have to hold the pedal down for a bit the get it to idle a bit then I drive normally for at least 20 miles then all is good.
