Subject:      Need Aux Air Valve (was Van Stalls Easily when totally cold.)
Content-Type: text/plain; charset=ISO-8859-1

So,
I broke my aux air valve trying to tighten the adjustment nut.  Doesn't look
fixable.

Anybody know where I can get another?  They seem pretty unavailable.
Anybody know of any that are interchangeable? The official part number is
bosch 0280140101  I've found a bunch of other bosch parts that also start
with 0280141 and just end in a different 3 digits.  Anybody know if any of
these work?
Thanks,
Wes
