Volvo S60 D5 has rough tickover only firing on 4 cyls?
My volvo S60 is OK at speed but runs lumpy at low revs. I have tried two lots of injector cleaner with no improvement. What is the most likely cause and answer please.
faulty injectors are a common problem on these,especially on high mileage engines,but check the top engine mount first, a worn engine mount can often give a false indication of rough idling on these.
