REANULT TRAFIC LOSS OF POWER BELOW 2500 RPM

[Hullstorage]

hi all, i have a problem with our 1.9dci renault trafic. when starting and you put on full revs there is lack of power. i.e. when setting off at a roundabout the van sets off very slow and needs a long time to build up speed. after you get past 2500RPM the van is fine...any ideas?? thanks simon
