2006 6.0 stumble
Hello guys,
Was hoping someone could help with a problem I am having?
First... Items I have replaced:
- New EGR valve
- New sensor
- New Fuel filters
- New Oil filter
problem:
while driving I have a stumble along with a small amount of black smoke at this time ( was white/bluish smoke ) previous
I have dis-connected the batteries to force the computer to relearn the EGR valve
the turbo spools up .. getting about 20 psi @ hard throttle and then about 5 psi after it goes into the final drive grear
speaking of which ... the stumble is always worst on the final drive gear
Any help will be greatly appreciated
Dave

I don't have any aftermarket gauges so I couldnt tell..... will have to take it somewhere to have that checked.
I disconnected the battery cables one more time in hopes that the computer would re-learn the EGR valve, but the code still came up.......Code P0402
Is there such a thing as an EGR pressure sensor on the 6.0
Dave
have you tried to read the codes

Well ...... I am stumped...
had about 1/4 tank so I decided to fill up.... after that it seems it is running fine now. I am going to disconnect the battery cables again tomorrow and leave them off for about 30 minutes and put them back on and see what happens.
had a fella on another board explain to me that I might need to clean a sensor located on driver side under the de-gas bottle that is attached to a stainless steel tube (what is this sensor called)
also another passage that is located on the passenger side that has a rubber tube coming from what seems to be a sensor going down to the passenger side of the intake (What is this passage called) ... its looks like a burred fitting that screws into the intake
Thanks

Those would be exhaust back pressure sensor and the map sensor tube. The first mentioned sensor clean the tube also.

Reason for asking is that I was driving home the other day from dinner and the motor seemed to be running fine, but I didn't have any boost....... about 5 seconds later the boost kicked in.

I have been having the same issues. Stumbling under load, erratic boost etc..., and no codes, the dealership was stumped, finally installed a VDR (vehicle data recorder) to try and locate problem. The VDR is a computer they program to measure certain parameters and when the problem occurs you push a button and it records all the parameters before and after the event. With the data they were able to determine that the issue was with the Variable Timing on mine.

been having a simular problem with my 05 6.0 it was spuratic at first then slowly became constant. I have several threads on here about it, a lot of people with a lot of good info trying to help. Unfortunatly I have not been able to resolve the problem. My problem seems to be injector related. Not sure if thats a possibility with your issue but your symptoms sound the same. I was instructed to check the Fuel injector control module(FICM). There a lot of information on here about them and they have a high failure rate. Good luck. let us know if you find the fix..

got home and pulled the tube......was blocked & also clogged at the base where the tube attached to the exhaust.
disconnected the battery cables ..... cleaned the tube and the port at the exhaust.....installed everything back and hooked the batteries back. Drove it for about 5 miles and it still has a studder after the tranny goes into final drive.
Going to drive it to work in the morning and see if it clears up any.

Had time to check the FICM
2006 6.0
4 pin checked pin nearest driver side fender
with key turned on without cranking = 48.74 volts
I don't have anyone here to cycle the key to check for voltage drop
Should I be ok with the FICM or is there another check I need to do brfore I button everything back up?
Thanks
Dave
