Engine smoke/rough idle

[Seanix]

After a few hours on the forums and youtube help videos I am at a loss and in need of some help/suggestions.
I have a 2004 6.0L completely stock.
Over the past 6 months on start up the engine idles but if I tried to drive it cold it would buck and jerk like it wasn't getting enough fuel. Once the needle moved on the temp. gauge the truck ran with no issues.
Now on idle the truck has a noticeable miss to it and it smokes. It always smoked for the first 15seconds after start before but now its steady. It smells like normal diesel exhaust also. I had been told that if it was coolant causing the smoking it would be a pure white and smell different and when you rev the engine it would get worse. When I rev the engine the smoke turns blue and black and it has never blown black since I have owned it.
What I have checked:
1. I connected a OBDII reader and it pulled no codes at all.
2. I removed the EGR valve and cleaned it. One of the videos said if the EGR cooler was leaking the bottom of the bore would be wet and it wasn't.

Any help would be appreciated.
Thanks

Search for Rev-X. I bet you will find your answer. Good luck.

Thanks Sargar, I bought Rev X today at the local diesel shop and changed the oil and filter along with it.
Drove the truck up and down the highway at highway speeds truck runs fine but pull up to a stop sign or redlight and the smoke is blowing like crazy and there is a miss to the engine. Will drive it some more as the Rev X site says I need to heat cycle the engine a few times over a couple days so I hope it clears up.

I hope the Rev-X helps. Still no codes?

check your batteries
check your FICM
if you have an injector dumping fuel, you can toast a piston pretty easy.

Need to get it diagnosed quick

Nope no codes as of yet. . .but maybe my OBDII reader isn't very good?? I am going to drive it tomorrow and if it doesn't clear up the next step I think is a stop at the Ford dealer to have them do a diagnostic to check the injectors properly.

I don't have a multimeter so I haven't checked the FICM yet. . .

Just had the truck diagnosed at the dealership they said #4 injector is not working and the EGR valve needs to be replaced.

Which leads me to ask. . .how bad is changing injectors??

#4 injector is on the drivers side, second one from the front. Depending on how mechanically inclined you are, it is not a very hard job and you can save a bunch of money. But by reading your post, I would leave it to someone with more diesel knowledge.

The very first step with troubles on these trucks is to verify crucial parameters are met....voltage, high oil pressure, fuel delivery, etc....not just throwing rev-x in and changing the oil. What about injector #4 is "not working"? It may be something that is easily fixed with an $8 set of o-rings. You have to ask them these questions or your wallet may be in for a ride.

Good Luck~

Thanks for the input. I will be doing the repairs myself as I am pretty capable but I know the most about small block chevy engines, this truck is used to pull my race trailer. I watched a video on youtube from a ford mechanic and it looks pretty straight forward. Luckily it isn't my daily driver so I can put it in the garage and pull it apart and take the time to look things over. My local dealership qouted me $2100 to do the work and the diesel performance place I deal with qouted me $300 for an injector sooo the math tells me I will save huge doing the repairs myself even if it turns out to be replacing the whole injector. The o-rings you talk about are you meaning the ones on the injector itself?
