I have an annoying problem on my 2002 tdci 130, after been on the overrun and if I apply light throttle as oppsed to booting it I get a missfire, that feels like the engine is going to stop, then it picks up if I give it some gas.
Definately feels like fuel related but I dont have a clue as to where to start, drives fine apart from that, no warning light or anything

Does it happen at the same revs? If so, could it be turbo related?

Doesnt seem to be revs related just trailing throttle, but not all the time only when been on a longish run
