2004 f550 6.0 want take fuel and pours black smoke
 

Was driving it was running fine never no issues came up to stop sign went to take off and would hardly go stomped it to floor and hardly nothing a few seconds later takes off like a rocket and pours black smoke once going runs good but when you mash it all the way kinda stumbles and pours smoke stop in park mash it and same thing nothing then wide open pouring smoke check engine not on but scanned it and it has p0404,p0603 & p1000 any ideas please help only 69,000 stock expect exhaust and banks programmer but returned it to stock when this started but didn't fix it same problem

p0404 is an egr code. p0603 is a kam code. p1000 is a obd system readiness code. the stickies at the top of the page have a 6.0 bible you can look at to see all the codes. i would take the egr out and clean it. see if that helps then check all the connections to the turbo. good luck

OK thanks I seen the codes. I just didn't know where to start I read about the egr problems in other treads but none seem to be having the symptoms I'm having but I'm gonna clean the egr and see if it fixes it I'll keep you posted

start with the basics also check the ficm voltage and batteries and just work your way through the easy stuff. im sure mdub will post in the morning with more to help you better

Definately sounds like a ERG valve is crudded up, it is located right next to the intake elbo and is held down by 2 8mm bolts, they take a little prying to get loose but be kinda gentle with it, don't want to bend it up.

Pull the EGR valve out and clean it. You might want to yank the turbo and recondition that as well (clean it).:c:

After reading this post and thinking about it. If im at a dead stop and mash it, my truck will hesitate for a second, roll coal and then my tires break loose and it goes like a bat out of hell. But when i just mash it it takes a second or two and alot of smoke before my truck GOES. I have an EGR delete already so what could this be?

Probably needs a turbo cleaning. Your EGR code is from the delete. Do you get a CEL from that? SCT is the only thing to turn the light off, the banks wont do it.
