This one is probably easy. Angela's '90 90Q20V did this for
quite some time, I finally got pi$$ed enough to track it down.

DO THIS WITH THE CAR COLD!

Slide underneath, follow the exhaust downtubes down from the
engine to where they make a 90 degree turn to go back under
the chassis. Notice the piece of thick "aluminum foil" that
wraps around the corner of the pipe. It is some sort of heat
shield. It gets loose and rattles. Grab one end with hand and
wrinkle/crush it a bit to make it stop rattling.

If it isn't this, sometimes the cat heat shield gets loose.
Try the same approach, or have a shop tack weld it, or just
take it off and don't park on any tall dry grass :-)

Normal for this car, much stiffer than my 100Q.

See #2.

When you pry it out of our cold dead fingers :-)
