Is this a test, Posto, or a real problem?  :-)   Come on, "it tries  
to start/catch".

Wylie certainly has it nailed as a fuel problem.  You can mess with  
the FPR or the filter,
but if you are serious, just go to the pump.  If you are going to dig  
it out, just replace it,
since you probably won't feel like doing this again real soon.

Brooks must enjoy working on the S6 from looking at the things he has  
done already, so
might as well replace the fuel filter and pressure regulator, and all  
the vacuum lines. They
probably need replacing since they haven't been mentioned yet.  :-)
