406 2.0hdi tick over probss

hello there

when starting the car it sometimes cuts straight away to get over this i have
to put my foot down which is not a good idea from cold.
when driving the car and i take my foot off the pedal it drops to around 900
revs and then drop drastically but pick up again straight away like its about
to stop but it never does.
a new maf ( mass airflow sensor ) has been fitted but it has made no
difference.
no error codes are coming up.

any help would be appreciated


thanks patch.

Can't offer any help I'm afraid but have had same model for 3.5 years and
have noticed the exact same behaviour on many occasions. Slightly
disconcerting, but never seems to lead to a stall so have always assumed
it's some quirk of the engine design.
