JTDm smoking & hunting

OK I'm sure that this might have been covered before, but I'm not certain where to start looking. My 147 JTDm has been beltching out a bit of a black cloud under hard acceleration for a while, but recently it has starting black smoking all the time and under with a hard kick down I lose sight of everyone behind me ! Whilst holding a steady throttle at 80 ish (2300rpm) the engine appears to be hunting or surging about every 1 or 2 seconds.
I'd guess it's one of the following - injector, fuel pump, split hose,... but where do I start ?

Just a startled bunny in the headlights of life...

I would run a decent fuel injector cleaner through her. In addition to her new hose.
