But now there’s a bit of a problem On full throttle through all the gears it runs perfect but when your in traffic and keeping the Rev range low say 1500 to 3000 rpm plodding along at 30-40 the van runs very lumpy and jerky and starts to smoke really bad and smells of unburnt diesel until again you use full throttle then it clears
So basically if I thrash it with my foot to the floor it’s fine until I have to drive at a normal speed then it starts
Has anyone come across this of have any suggestions
