I have not rebuilt injectors yet.  I did, however, test the breaking
point and spray pattern using Bosch injector tester.  I have given up on
the 1.6D and purchased a 1.9D, so now I have brand new injectors.  It
only has 400 miles on the clock, so I'm not at all interested in trying
to calculate fuel economy.  I'll be very surprised if it isn't 25-30.
If I come up with some amazing mileage figure after the 5000 mile mark,
I'll be sure to let everyone know.  I'm also quite familiar with pump
adjustments.  I have a mile-long hill leading to my neighborhood with a
45 MPH speed limit.  I put the pedal to the floor in 4th gear (5 speed)
and look for smoke when climbing the hill.  My 1.9D loses 2 MPH from
bottom to top of this hill.  I adjust the pump in 1/16 turn increments
until the smoke just disappears at full throttle.  FWIW, the 1.6D would
drop from 45 to 33-35 MPH on the same climb.
