Deceleration valve

[Peter Henriksen <peterhe@microsoft.com>]

Hi all,

through a little further investigation on my part of the problem I have
with the 200 dying on deceleration, I have found out that it might be
the "deceleration valve" (I was told this by a dealer mechanic). Does
anybody know what it does, where it is, how I can possibly test it and
if it can be replaced as an individual part? (Whew.)

Thanks (in advance).
