Cat failure now loss of power

["Remi Kwan" <kwanremi@nortel.ca>]

Hi,

I had a cat problem diagnosed on my 1994 90 Quattro (12v V6) and have 
been waiting for the dealer to do the work (earliest was monday :( ).  
In the meantime, the rattle I had has quieted down but the car has
lost power and won't rev like before.

Could this just be the ignition figuring out somethings wrong and doing
something smart with the timing?  Or could there be other damage related 
to the bad cat?  Maybe I love these cars too much, but I'm starting to 
have nightmares about clogged exhausts and valve damage...
