Hhhmmm, got a little problem developing with my baby.
Over the past few days it has tried to stall on starting in the morning. So far it has kept going but its getting worse. It'll run ok but hesitate a bit for the first few hundred metres and then all will be fine.
Had exactly the same prob with a Lancia Dedra a couple of years ago, and it turned out to be a faulty engine temperature sensor.
FYI I was looking back at some old posts on a simailar subject, and the Intermotor code for this sensor for the V6 is IM55460 (info kindly supplied by Jimmybob)
