To me it sounds like a little air in the lines. Mine does this from time to time, a quick touch of the throttle to bring in the high idle and it settles down.
Haha, ya it s usually pretty chilly up here in the winter months. I still have the factory idiot gauges but I trust they would be good in telling if I'm overheating. last winter I had it
Thank you...I was about to write up a reply basically saying the same thing that you are. While you don't want to drive the truck like a rental immediately after lighting off, idling for a long period of time to warm the engine up is one of the worst things you can do. First, it'll take much longer to warm up; second, a long period of low-idling will result in unburnt fuel getting past the piston rings and into the oil. This is true with any diesel, really...although, at the same time, I would be gentle with the engine at least until the high-idle kicks off...That being said, it takes a while for these engines to warm up, and it takes a very long time to warm up just idling. They are very fuel efficient while idling and do not generate a lot of excess heat. The fastest way to warm them up is to put a load on them. i.e. drive it after it smooths out.
