Hello and Welcome to justanswer...

From your description of the fault - it would appear that you have one or more , faulty injectors..

Injector cleaner is good and will help but if an injector is mechanically or electronically faulty -then no amount of cleaner will help Im afraid...

You need to take your vehicle to a diesel specialist who will have the equipment required to test the injectors for faults and then rectify whichever one has failed -either by repair or replacement...

I Sincerely XXXXX XXXXX have helped you - Please ask if you need more help...

Kind Rgds, MIKE
