[V6-12v] No Idle

[Nathan Widmyer]

I went to start up the ol Audi last night and instead of idling at
it's usual place, it went down to about 200RPM's.  I gave it some gas
to feather the engine and the tach went up then back down and the
headlights dimmed.  I gave it a little more gas to feather then hover
the RPM's at around 2000 and then released the clutch.  I let it move
about a foot then pushed in the clutch and it idled properly from then
on.

I was in the path of the recent tropical storms as of late, we just
got a lot of rain and I didn't get a chance to put the skidpad back on
after last months adventure in oil changing.  I don't know if these
two circumstances would effect what happened but it's the only things
that occured out of the ordinary.  Can anyone explain to me (and us)
what happened?
