hi, i have a 52 plate peugoet 307hdi 110 hp and its started with this intermittant spluttering fault. it doesnt lose power an i seem to be able to 'accelerate through' the fault if that makes sense. But if the car stays at the same revs it jus splutters away. I've tried an injector cleaner but no diff. This problem can disappear for wks at a time then when it starts it happens for 2 or 3 days. thanks in advance for any help anyone can give me.

To be honest...I don't know about the car itself, but diesel fuel filters have to be changed at the required times...they do get dirty quick and hold water.Other than the cleaner added what was done?
