1.8 Zafira stalling problem.

[col]

Why does my engine often stall? Quite often when slowing to stop,I
brake and dip the clutch, the revs drop below the idle and it stalls.
It likes to do the same when reversing too! Thanks.

though this is for a vectra, the basics are the same

Clean out the throttle body around the butterfly.
