Vauxhall Vectra 1.8 GLS petrol 1999.
Crank it over, with no throttle and sometimes it fails to fire up, hot or cold. When it does, it gives three or four periods when the engine almost (or sometimes does) die.
Stop for a roundabout or lights and again it does this almost dieing, before finally settling to a nice steady tick over.
I have suggested a sticky injector, or perhaps low fuel delivery pressure - anyone agree or can suggest alternative ideas please?
The owner has been told it might be a known problem which needs a modification via reprogramming the management system.
