406 hdi holding back when accelerating slowly

[ianandpaula33]

Hi all, can you help got a 1999 2.0 hdi 406 diesel which runs fine except when you set off slowly and dont give it too much gas. It seems to want to hold back and die alittle. Give it wellie and its off no problem. New filters all round and oil. Nothing on the engine management side of things. Any ideas Thanks Ian
