Astra 1.8 16v (1999) which will let the revs go under 500 when I dip the clutch. It will nearly always stall after a little engine judder. Occasionally it will recover itself and go back to normal (unitil the next time the clutch is dipped).
My local garage say that I need a new Air Mass Meter ??
Anyone any experience of this, I've seen a similar post with a 1.8 Vectra.
All ideas welcome !!!
