In an effort to extract the last bit of performance from that marvel of
Teutonic precision engineering (no, not a Pfaff sewing machine), I checked
the fuel system pressure of my 2.1L today.  If the truth be known, I was
changing plugs and it seemed to be easy to do.  I found the pressure at idle
was 34 PSI with vacuum and 40 PSI without.  After shutting down the engine,
the pressure dropped to 30 PSI and stayed there.  Now, the Bentley calls for
pressures of APPROXIMATELY 29 PSI and 36 PSI, respectively, with an at rest
pressure of 29-36 PSI.  Since the system held pressure within the range
specified, I would think that the regulator is still good, just a little high
on the setpoints.  Does anyone know what kind of tolerance to expect for the
regulated pressure?
