Idling in cold weather?

[6.4PSD]

Last night it dropped down to 25 and it snowed so I thought I'd start my truck and let it idle for about 15 minutes and when I walked back outside it sounded like it was about to die so I turned it off and restarted it and it was fine but didn't sound good.

Is it bad let the 6.4s idle?? Straight pipe and Spartan tuned if that makes any difference.

Thanks

Did you check for codes? You sure it just wasn't surging in high idle? That's pretty common for tuned 6.4's.

My truck idles ALOT! Never had that issue. Were you using the standard high idle, or do you have a high idle hooked up to your upfitters? Sometimes my truck will make a very minor loping sound if it has been idling in the standard high idle for more than 20 min. If I kick the upfitter switch high idle on which bumps the RPM's up another 200 rmp or so it will go away.

I idle alot as well, and as Jeff mentioned does surge when its cold. (25 isnt cold either btw )

My truck idles alot in the winter time. Its fine. At 25 though you don't even have to worry about it. Don;t even have to plug it in. 25 is warm.

I'm not even sure it really needs plugged in. I've cranked it over in the morning at -10, at 5 at 15 like both days this weekend, at 30, 45, 55. It cranks the same at any of those temps on mine. I guess below -10 things can change drastically but most don't deal with those numbers often.

If you can plug it in, it is better for the motor in the long run, but if you cant the truck will still start.
