[200q20v] left over parts

[Bruce Boeder]

Thanks, Mike, I'll try the first.

The boost gauge is showing boost up to 1.8 or 1.9 (I can't remember which)
and so I don't think there is a vacuum leak.  Watching the boost gauge has
been fun.  I wish that our TT Roadster had one.

Incidentally, interesting little side story about the TT.  Check engine
light went on last Wednesday.  Car seems to be fine.  Called dealership
service. They suggested that it might be a loose gas cap or gas cap gasket.
Checked that several times. Light still on.  We're heading to the North
Shore of Lake Superior this weekend and so I'd like to get whatever this is
diagnosed before we leave as it is kind of a long way between towns up
there.  Dealership says "we're making appointments for July (yes, July!)
16th right now and can't guaranty that we can look at it."  I don't know how
long it takes to hook one of these up to a diagnostic computer but it can't
be long.
