Yeah, I would say that something is up with the truck. Even in -40 weather, my 03 doesn't miss a heartbeat. When it is cold, the pilot injection does turn off and you'll get a heckuva rattle out of it. Is this possibly what you're hearing?

Routerguy, you should know that the "gentlemen" on this forum never forgive the smallest error. So suggest you modify your 30 foot engine to an '03. That is, unless you enjoy the ragging. ;D

Thanks I didnt know I could do that..

 

Yep!!! ;D

 

I'm with Rod, mine purrs along just fine even at -20C. I'd say your dealer isn't in touch with what cold is! (Maybe he's from Texas :)

 

Mine does the same thing, even if it's not cold outside. It just basically has a rough idle until it warms up but it runs great once I hit the accelerator. I haven't really paid attention to see if it does it all the time or only when it's warming up. I will worry about it when it quits running!! Maybe our trucks just have a better, more lopier cam!!! (Is lopier a word???)
