When I first start it it varies between 1800 RPM and about 400 RPM.  What gives.   Also, that big, short vacuum hose next to the intake manifold keeps colapsing.  IS that normal.  I borrowed one off of another Audi and it did it too.  Are all these problems inter-related.  I think they are.  On Hot days it even dies when I stop at a stop sign sometimes.

sounds like an idle stabilizer to me. with key on engine off it should
be buzzing to the touch.It is normal for it to buzz on and off.
