Subject:Re: vacuum and the fuel pressure regulator?

Along these lines ( no pun), I have been having a slight hesitation in
the 2200 rpm range, possibly related to this...the car runs PERFECTLY
while cruising, but, under certain decelleration conditions, it begins
to "buck"....usually in second gear, around 2200, and usually
decellerating...when I try to give it gas, it begins to buck,slightly
at first, then more violently, until I take the clutch off and give it
more gas...it then out, and runs normally.
Could this be the FPR going bad?  I have repaced the injectors, plugs,
wires, fuel pump, filter, air filter...
Any ideas?

Thanks
-Rich
