How about if I bring the noise to you?? :)

Notes:

1. It doesn't happen when the car is cold (REALLY cold; within 30-60
seconds of startup I'm OK, after that the noise shows up).

2. It only happens on deceleration.

3. It's much more pronounced when the idle switch is engaged. If I
decelerate without hitting the idle switch, it's virtually
non-existant.

4. The noise is worse now that I've got the Lambda system working
correctly. Go figure?! :)

5. If I dial the mixture rich (way rich, at least 1/2+ turn beyond
where the Lambda system gives up trying to regulate things), the noise
goes away. But I want to solve this problem right, not just patch
things up.

6. Lastly, it sounds much worse in the recording than it really is due
to the echo off my garage walls. But you get the point. It's
irritating and doesn't present my DeLorean very well in traffic.
