can anyone give some advise my 406 hdi 110 has rough idle. sometimes its ok but most of the time it runs rough ,when i rev it up its a bit lumpy till it hits the turbo then its ok ,there has been no engine management light come on to check it ,ive done a flow test to the injectors that was ok .chang...

With the engine mount gone the engine still would not run lumpy its not that

Can anyone help i have a y reg 406 hdi exec the anti pollution light is always but the power is fine. but the last few days its lumpy on idle ,did think it was the particulate filter but this model didn't come with it any ideas thanks
