Power loss while gentle throttle
#16
he may no know how a FPreg works nor just how important it is on older cars. this car has no fuel pressure sensor ,like all new cars have.
the new cars run a fixed pressure, and this reg, based on vacuum is not important on new cars .... they forget or never learned it.
i wish you luck and , a solution fast.

the reg can have a stuck valve. (open or closed or?) many are, this old or temperamental.
the diaphram can crack. and get near 3bar.
if it sticks at say at or near 40 PSI (3bar)
it will over fuel. at most times.
causing rich misfire, normal idle is 2.1bar.

3 bar fuel pressure is only good, at WOT. . (to push hard against the high atmospheric pressure of 1 bar)

btw ,nice write up on symptoms. best ive seen.
