I've had my 200q20v for three? weeks now, in addition to a stall on
the pre-purchase test drive, I've probably experienced a total of six.
Your problem sounds similar to mine when I get it up to temperature,
maybe you can create the failure in the way I've experienced it.
They seem to mostly occur after I've blipped the throttle and made a
downshift while coming to a stop. It dies when I put in the clutch and
come to a stop, e.g.: hard on throttle for a sec, grab the gear and
brake, not touching the gas peddle again. YMMV, any engineer will tell
you that trying to show somebody else an intermittent problem is a sure
way to a headache.
I've not had much time to fiddle, the steering rack and fear of using
the old headlights at night used up all diagnosis/repair time to date.
Other listers have covered about everything I've come up with in the
Bentley that I plan to look at.

Anyone who cannot cope with Mathematics is not fully human. At
best (he) is a tolerable sub-human who has learned to wear shoes,
bathe, and not make messes in the house.
