Volvo D 13 iShift Clutch issue???

it is very possible when it looses crank speed it looses all sense of what the fuel delivery and boost.so that would be the first step .

 

Is it doing under load conditions or all the time?

 

Looking to buy my 1st truck. I shift or smart shift ? And what motor option. Looking at 2011. And 2012 Volvo and freightliner. Both 300k on miled

 

That points more and more to injector cups. Take it to the dealer to get the definitive diagnosis.

 

+1 more agreement on those f%^&ing cups/injectors.

 

Ok the best year Volvo's would be 13 and 14. The 11 was the first year of Def and i would stay away unless they fixed them. Same with 12.

The Shakers had some issues as well I don't remember if the 12's are the better year or no but again issues with emissions.

 

5k to 6k at the dealership. Sometimes they run specials just depends where you end up.

 

just before you start on injectors ect and jumping to conclusions check the wiring harness the boost sensor on left side joins in to harness i had one 2 weeks ago everytime he powered on from light or uphill the boost sensor would be getting power and the wires rubbed through for the crank sensor and he was getting surges of power while driving. just don't start throwing parts you need to diagnose and check things first
