doblo 120hp gutless

has any one else had a loss of power almost like a misfire on there engine that is the 120hp not any of the others

well sometimes it is fine but then it will miss a little bit and the instant mpg goes down to 19 at 100 mph when it was 40

if anyone has had this on there's what was the answer in the end

fiat technical have been out to the car changed the injectors and map sensor with no difference

mabey the maf sensor or something

can you not check air flow meter & egr valve?
