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.

You have to insert a small piece of 1/2 inch copper pipe into the vacuum
hose right before the elbow near the intake manifold to kkep it from
collapsing. You will notice that the other end of this hose connects to
your idle air regulator. Very important that there are no leaks here or
you definately will get erratic idle.
