Coupe Quattro 20V Carbon Fouling Plugs

[Ben Swann]

OK Making sure this got to the intended recipient brettfairbanks at verizon.net as I
screwed up on the original reply address. 

Basically what you are saying is what I meant sort of - somehow the FPR fails and dumps
too much fuel in.  I can certainly see how a seal in the regulator fails or leaks in
such a way as to dump fuel directly into the head, particularly if the injector seal
allow for fuel to leak by or to pull fuel through the vacuum control port - which  now
as I recall is how I think the failures I mentioned earlier were occurring.

Possibly....but given:

...it sounds like maybe the FPR has completely failed and is leaking fuel into the
manifold via the control port.  I can't think of how else you could get fuel in there.
Certainly not from the injectors, yes?
