2011 Volvo 670 D13 Engine Power Loss

fuel filter

 

well the first thing i would ask, is there any codes popping up when this is happening in your engine ecu. that will tell you if you have electrical issues or if you have something mechanical. to me it sound like something that would be mechanical but you're not giving out to much info to go on.

 

also when they replace your injectors did they replace cups as well was this done at a volvo dealer or was it done at a shop. is there any warnings coming up when this is happening like a derate or something of that sort. y were your filters replaced did they have a crack or were they just throwing parts to figure out maybe what it could be. what kind of milage do u have on this thing.

 

Do you have any codes popping up on the dash board? Did you change the EGR's?

 

well i would highly suggest to replace injectors and cups at least make sure they properly check and see that there is no pressure in the coolng system and that no fuel or anything like that, but for this type of job you either go to place that have dealt with volvo engines for a long time or volvo dealer i don't know where you are located but there is not to many shops that deal with volvo specialy when it comes to injector cups and injectors

 

If the truck runs fine after stopping it highly unlikely it the injectors. A bad injector is bad all the time. If it was my truck I would replace the wiring harness under the valve cover going to the injectors and engine brake. This harness get soaked with oil and causes all kind of problems any small crack will cause a short and volvo are know for this

 

Spn 1127 is turbocharger intake manifold pressure,so check turbo,hoses and pipes for leaks.

Spn 102 is engine intake manifold pressure,check sensor and harness.
