Loss of power - turbo problem?

[G Boyd]

Two things i would look at.

First change your fuel filters and put some conditioner in your fuel. Where is the Racor guage sitting?

Second take a  look at your hoses that run from the turbo back to the cold air intake. If you have a leak in one of those hoses it will cut your boost under demand.


That is a starting point that will cost you nothing.

Happy New Year

On the second day of a trip from Iowa to North Carolina before Christmas and during very freezing temperatures our coach began losing power during acceleration from lower gears and while climbing hills in top gear.



The lose of power is severe and I can feel the drop off and see on the turbo boost gage drop 3-5 psi as it engine tries to produce more power. It appears the turbo boost 'catches' and tries to build again, but it drops off the 3-5 psi and continues this cycle.



I did not get any lights/codes, so I'm unsure what it is. On the flat where turbo boost is not `in demand' it cruises along fine.



Any ideas, experiences or suggestions where to look first would be appreciated
