2006 volvo d12d injector problem

3-450 max its at the bottom of the range egr is "broken" and no boost leaks new CAC restrictor removed between turbo and manifold restrictor removed in front pipe and straight exhaust it is not that loud has no smoke no running issues and very low economy have thought of replacing injectors and cups but get worried due to your exact problem. prior owner replaced harness & turbo exhaust never gets up to a 700-800 unless im heavy pulling a very long hill and still its not that hot coolant temp in summer is about 170 on the dash winter is at the bottom of gauge but will make heat so hot in the truck you 'll have to open the windows

 

Have the dealer swap injector #3 and #6. If the fault code moves to #6 then it's the injector IF IT DOESN'T and stays injector #3 it's the injector WIRING HARNESS....

 

OTR kit was installed by last owner when egr valves came apart and turbo ate them. has a mid code that will not delete i believe it was a position code for the egrs when they broke and kit was installed without resetting position letting the computer always keep it hard set

 

where are you finding 250 a pair? id swap the broke For that price. the cooler has a resister wired to read correct temp range

 

it took almost 18 months to figure it out on my d12d after changing #3 a few times and it working for 3-8 months each time.. the dealer suggested the swap (3 & 6 are the same part) 4 months later #3 coded again... change the harness... 300k later no problums
