Glow plugs will cause smoke on a cold start. It will run crappy until it warms up. Diesels don't like to be run cold, they don't make a whole lot of power when cold. Let it warm up before you call on it to do some hard work.

Colder than it is in Texas right now, even in the mornings. Below 50 degrees F.

sticking/varnished fuel injectors will cause a rough idle and then smooth up when they warm up.the early trucks ford designed a reflash to help improve the cold start.the rough idle statagy was designed for trucks that missed at 60 degrees and below .

I have an 05 F-350 that was recently updated so the injectors all pulse after the truck is shut down, draining the fuel out of them. You can hear a real quick ticking sound for a split second if you pay attention. This supposedly helps with cold starts.
It's supposed to be a factory reprogram from Ford.
