Sorry about that.
It's puffs on the exhaust.
You can see the engine shaking a bit at an idle, example after it's started. Once it warms up, the shake is still there. You can feel it when driving between 900-1400 Rpms. Once it gets above that the shake goes away.

Shaking occurs at idle.
Has no horsepower until you get the truck above 1500 RPM's.

 

It sounds like you have an engine misfire condition.
Might I suggest you start a new post to avoid all the 30 some posts in this thread.

 

Well folks long time since I've been on here...The truck it lives finally had to take it to a mech. It was for the most part the ICM. But i have my baby back. And i do thank you all for your help.
