I guess I should check in more often haha.

Coonhunterjoe in reference to your question...

My symptoms are:

I can not let the truck idle, in the mornings now that its cold i let it idle like 5 minutes to warm up a little and thats it. When driving, before up to operating temp, i try to keep the shifting to a max of 2000 RPMs until warmed up.

The problem is one it warms up, It will start hesitating, bucking off and on under partial throttle (i will say "half" throttle). It will blow white smoke like crazy and have no power, untill i floor it and it "clears" itself out and is fine. But if i dont constantly floor it i have this hesitation, bucking/loss of power issue.

Now, for some fill in info.

This has been going on for awhile, through numerous fuel filter changes (both filters).

I took it to the dealership and they said it was a bad EGR valve and replaced it. It seemed to help minimize the problem, but the problem never went away. And now it is getting progressively worse again.

And as far as i know everything from recalls and TSBs were done to the vehicle.

So there are the symptoms.....lemme know whatcha think when u have a chance.

Thanks for any ideas
