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.

hello Peter

sorry for the slow reply but i have had a mechanic mate of mine look at the car and he sorted it grand style it turned out to be the high pressure sensor for the fuel rail its situated behind and just to the left of the fuel filter it reminds me of the old oil pressure sensors but a little bigger.i can,t believe the difference it made to the car its never been better i have had this car over 3 years now and its never been so good.I don,t know the cost of these sensors as he had a good used one on his van he only charged me a tenner in total.

hope this helps

jeff
