psd 6.0L rough idle, grey smoke, no power cold start.

I have a 2005 psd 6.0l and the past few cold mornings, my truck ran really rough. there was gray smoke coming out of the exhaust and it seemed the truck wasn't running on all cylinders. Once it warmed up, it sill didn't seem to make full power but the gray smoke did go away. Her is a video i shot the over day on a 39 degree morning.


What do you think it could be? Glow plugs? Injectors?, etc. I have an innovative diesel tuner with a 4in turbo cat delete. I really appricate the help.

Ive got an 05 that was doin close to the same thing except it would do it regardless of the outside temp. It would crank and run rough and skip and miss till it warmed up then seemed to run ok. I ended up having 4 injectors go bad. I had to leave it at the dealer overnight for them to scan it bc it wouldnt show anything once it warmed up. Hope this helps

I have an 05 that was doing pretty much the same thing. I took it to the dealer and left it over night then meet the tech and rode with him that morning. Turned out that the turbo was stuck, he seem to thing when the EGR cooler blew all of the coolant going threw it caused that. It also has 3 bad injectors they replaced at the same time. The truck had 50k miles on it and was covered by warranty so I don't know the cost.

I have an 05 that starts fine. However when you first eccelerate it spits and sputters for few then runs fine. Unless it sets for 5 or 6 hours it will run fine the rest of the day. The next day it does the same thing. It did this a couple of years ago and Ford put a new injector module in it. That fixed it for about 2 years. Should it need another one aleady?

Mine was doing that. Cranked fine in 25 degree weather and idled great. Felt like a brahma bull when you pulled out on the highway until you got to operating temp, then it ran perfect. Ordered rev-x and it cured about 85% of the problem in the first hour. Got a little better with some miles on the rev-x. I'd say I'm about 90-95% cure on that. Really it's injectors(stiction) that are going to go bad. I am going to try the rotella 5t next oil change and see if it fixes the last 5%.
