Bye bye 6.7

[RichardBush]

I have a 2008 6. 7 it has went from running very well to running like you cut to of the cylinders off, last time i pulled my 12,000 lb 5th wheel camper i used 32 gallons of fuel to 200 miles. I have had it back to the dealer 2 times already and it runs worse each time i get it back. it won,t even spin on wet roads now.

What codes are you throwing, its probably your turbo sooted and needs replacement. The reg trucks need to have them cleaned or replaced.

I know this is not going to seem normal, but have you had the techs check for proper ground, or did you change something under the hood? A friend of mine had his 02 4X4 CTD start to run real sluggish and he was prepared to change out the injection pump as a non warranty issue. ($1500. 00) He took it to the tech I recommended to him and they told him every thing is OK, just check for loose grounds. He found a loose ground at one of the batteries and it solved the problem but still seemed slightly sluggish and he found another loose ground (?) and it is running as good as new now. No codes were thrown that I'm aware of.
