What Timing!
I can't believe it!I'm going to get my new 07 6.0 tomorrow and I'm driving my 04 6.0 today and I'm sitting at a stop light and go to hit the gas and the truck will not move......AT ALL!The thing is still running and starts to smoke white and gray smoke so bad I couldn't even see the bed of my truck.I keep hitting the gas and it keeps falling on it's face,after about 2 mins of smoking and not being able to move one foot I put it in neutral and rev it up,It rev'd up, I put in drive and took off.The thing has been perfect since.
What do you guys think happened?This late built 04 6.0 has been GREAT to me since I bought It new.She's only got 17,000 on her but it's been 17,000 FLAWLESS miles,until now.

One more thing,Assuming it's the egr valve sticking,should I look into disconnecting it on the 07 6.0?

Did the epa people think that it worked well as well with diesels like it did with gas burners even though they are two totally different animals? I really don't see the logic in having that for diesel engines, unless I'm missing something, please tell me there is something to their logic.

Ok, but then why do we hear of more egr problems in diesels and I haven't heard anything like an egr valve problem in a gas vehicle(other then the obvious difference in the types of fuel)? I know my parents and my friends that drive gas cars haven't ever has a problem with it and I know one car to have 150 k on it and it seems when there is a problem in the diesel, it's very dangerous if you have an egr problem in the middle of a busy intersection. To me, in order for it to work, it should: A. Do what it was designed to do and B. Other then normal wear and tear, it should not fail. I have heard(if you can take them on their word) of people going thru 3 of the valves in the first year of owning the truck.

i agree with you 100%. nox is alot higher due to the higher combustion temps. egr helps lower the nox by lowering the cylinder temps. the egr valve performs like it should and it does not fail, it just malfunctions. when it sticks, kit is usually due to excessive idle time and poor quality fuel. now with the latest flashes, egr flow is greatly reduced because of the reoccuring issues. some people have had alot worse experience with these trucks than most. mainly because they are not operated correctly. the 6.0 and 7.3 are only similar in the fact that they are a diesel, and some people think that they could just idle these trucks all day. i had one that had 1 gallon of fuel in the oil because they idled the truck so much. the emmisions on these truck are horrible. the new ulsd fuel will make this issue better and the fuel should have been out long before now.

I had the EGR go out on my 92 F-150 with 4.9L I6. It was expensive to replace. The reason they go out on the 6.0L Diesel is for two reasons...first, the exhaust is dirtier, so it 'gunks' up faster. Also, there is not enough power in the motor that moves valve. I read about the new 6.4L Diesels that the EGR valves have been moved up in power. The 6.0L is at 20N. ( I don't know what 'N' stands for ) but the new EGR valves have 400N to move the valve. That should fix the problem. I'm going to let mine idle all day just to test it.

Gas or diesel, Ford is notorious for EGR problems. I had 2 go in 90,000 miles on my '97 F-150.
Also in fpd7's post "N" stands for Newton. Which is a common way to measure a unit of force. So going from 20n to 400n is a substantial increase in force to move the valve.
