i have a 07 plate 120 bhp multi jet doblo with 42k on the clock,it is well serviced and hasnt gave me any probs regard dpf etc but i have a problem sometimes that the engine almost splutters when running about in traffic and i have 2 change down gear as it feels that it might stall the engine.when i accelerate hard the thing goes well.has anyone else had this problem? i am wondering if a remap might help.there is no warning lights on the dash and the car has had all the filters changed recently so i wouldnt expect it to be caused by lack of servicing. thanks choc
