New to Powerstrokes and have a problem....

[tfrostcoupe]

I just purchased a 2004 6.0 Auto Superduty and it has been running great until today. I was on my way home from work and turned a corner but when I got back on the throttle all it did was bog and dump black smoke out of the exhaust. It will bog and chug smoke and then eventually catch up and take off like normal. If I just rev it up with no load on the engine it works great but under load is when it is acting up. Any assistance would be greatly appreciated. Thanks, Brian

Id check EGR Valve. If its injectors would Idle and run like a gasser missing on a cylinder or two. Id go with EGR Valve though. You can try to clean it but Id just go buy a new one kinda spend $311 at O'Reilly Auto Parts

wouldnt a egr valve throw a code? just wondering because i am having the same problem and i have no codes

[powerstrokemonster]

most of the time there will be no codes on an 04 with egr just remove the 2 bolts pull egr valve out and clean with carb cleaner youll be alright

Thanks for the info, I thought it was kind of strange that it was running great and then all of a sudden run like crap without throwing a code. I was doing some research on previous posts and it sounds like you guys are on the money. I will try pulling the EGR valve out tomorrow and clean it up real good with carb cleaner. I will post up if it cures it or not. Thanks again, Brian

It seems that it was the EGR valve. When I pulled it apart the valve was being held open by some chunks of carbon. I cleaned the hell out of it and re-installed it and the turbo spools up alot faster now. It is running better now than before it messed up! You guys are awesome and I really do appreciate the advise. Thanks again, Brian

I did that with mine and worked for like 300 miles then went to crap. I had to get a new one anyone. Maybe you get lucky

[chuckles]

best bet is to delete EGR system completly.

Can we get a full description on how to delete it? Also, pros and cons to doing so.

[tfrostcoupe]

Has anybody used that delete kit that is being sold on e-bay? I think that it costs around $150 and the description says that it comes with everything including instructions. It leaves the egr valve in place but blocks off the cooler and the exhaust from running through the intake. It seems to be a cheaper way to reach the same goal. Let me know what you think, Brian
