Super high idle when cold?

[scummins]

Remote started my truck this morning, walked down stairs and fed my cat, came back up and could hear my truck idling really loud and there was white smoke everywhere. I killed the engine via remote, finished getting ready and went back out with the key and restarted the truck. It was still idling high at around 1100-1200 rpm. I was freaking, thinking it had something to do with the update I did to my mini maxx yesterday. Put it in drive and it dropped to 700-800. Drove to work and it was back to 600 rpm at idle.

Is this normal for super cold temps? This is the coldest morning that I have owned the truck. It was 6 degrees according to the truck display and this was the first time this has happened. I can't imagine it's good for the engine to rev up when dead cold like that.

Yes the truck has a high idle on it I think it kicks in when the temp is below 15 or 20 degrees outside. Nothing wrong with it at all.

trucks since 7.3s do this.
It's fine to high idle when not under a load

I made my Samsung SGH-I997 send this.

I see 1100-1200 rpm every night after leaving work.

the high idle should kick off once you hit the brake

Something must be wrong with my truck then. My high idle kicks off when you shift into gear.

Thats when mine does it with the factory high idle too.

I did the high idle mod to my truck to help warm it up when its colder outside and it idles up to 1100. Helps it warm up faster and at when idling for a long period of time can prevent wet stacking.

Mine does the same thing. I have mine plugged in every night now below 20 degrees.

I work night shift, so my truck sits in the cold while i am at work.

But at home it gets plugged in while it's chilly outside.

So you guys are saying hitting the brake doesnt kick down the high idle? That doesnt seem right.
