My 6.0 has multiple sympyoms hesitates when taking off from stop if setting very long at idle and blows out black smoke when I excelerate and then runs fine. Also lacks power until warmed up acts like turbo not spinning up.

 

The vanes are stuck in your variable vane turbo or the control wire is unplugged from the turbo VGT control valve but you may have Faulty EP sensor, VGT control valve slow to respond, Stuck VGT valve, faulty PCM.

 

How many miles are on the truck, how often does it get used, and what is it primarily used for?

Sounds like stuck turbo vanes to me. There is a cleaning procedure you can do yourself.

Thanks for response. New to diesel repair know just a little. I drive 3 to 4 times week mainly used for towing 5th wheel. How do you clean the vanes?

 

Click on the link I posted in my last response that says "Diesel Technician Society" it tells you in detail how to do it....

 

Ok thanks I found that I have 78000

 

It takes some time to do, but cleaning the turbo certainly wont hurt anything, wont cost nearly anything and is a good way to eliminate possibilities.

 

Thanks Mdub707 I've been reading ur DTS and it's been real helpful will buy neccessary parts today.

 

Let us know how you make out with it.

 

also mine did that too and it was the injection control pressure module that was doin it, took off from a stop light in Salt Lake and just clouded the entire intersection, needless to say people werent happy ha
