High-pitched squeal...

As I discovered this weekend, it can also be a vacuum leak.  I had the hose
that runs between the valve cover and idle stabilizer on my '87 5000s split
and it made a sound similar to that of a dead "alternator bearing."  I made
a quick trip to the nearest salvage yard with $10 in my pocket and was home
with a replacement hose in hand and $5 in change in less than an hour.  Who
says Audis are expensive to maintain? ;^)
