RE: Does a 3rd gen 5.9 cummins idle up automatically?
Working in the far north we've seen (in past winters) temps of -40F for a week straight!! Even with the truck "plugged in" she still runs rough. I usually let her idle for about 5mins then kick up the high idle feature to about 1200rpm for a few minutes more, she smooths out and I usuallydrive off slow to warm up trany and pumpkins! Let the ferd guys laugh... have ya ever listen to a ferd rattle when its cold? They sound like they're about to fall apart!! They have the most disconcerting rattling and knocking I've ever heard... I tend to keep my distance from em, for fear something may come flying out from under the hood and hit me! [:@]
