When I start my truck on a cold morning 30 degrees or cooler, after a minuite the truck goes into a high idle. This is every cold morning. This just started since the cold weather came to my town. My truck goes through regen every now and then. I can tell when it regens.............Anybody else?

my dad's truck does the same thing, I think it's just to help it warm up faster.

My 2000, 7.3 does that when its below 40*. Just helps it warm up and idle smoother.
