remembering what I said as any mech would or car restoring person or shop would say
no 1995 car has 1 problem not one, unless seen in a autoshow (contest ing for perfetion etc.) or museum or the like.
none.
that is ASSUMED always, and is expected.
16v mpi , new fpr for G16B mpi, and no other cars or engine or years.

Got the new FPR on last night, 40 psi key on 40 psi idle, 38 psi during acceleration but still bogs and runs worse than it did before.

so 40 and 40 are wrong and so is 38
with good FPR now we see the truth, for the first time.
why did you skip the shunt test.
why not do vacuum reading as the same to, so prove see, vacuum is right ,even to the point of using 50cent Tee fitting on the FPR vacuum line!
if vacuum is good. IDK it is.
then the pump is failing.
the fuel pressure is wrong, and most not be like that at all.
it looks like one of 3 things wrong, (lack of testing data , no vacuum readings same time)
1:new FPR is bad, what brand was it,? I'd say not bad but any skilled tech never never assumes, he tests and proves what is wrong.
2: vacuum not reaching FPR, common on all G16B ,and the vacuum nipple is packed full of EGR CARP plus PCV crap, call it double gunked and crapped out.
3: weak pump if shunt fails, 55psi is par. not 40. never 40 ever.
one other tests not done is:for sure shunt test next then.)
at idle, 800 rpm
we remove the nipple fast,. and connect my hand vacuum tool,all shops have this tool or fail.
we run the FPR at all vacuum points for sure 3.
we run 0 hg , engine will want to run rich and misfire. fuel pressure is now max. spec.
we run 20 hg( par for idle)
we run 26 inches HG, to see if FPR runs right on the whole line of my graph posted here. fuel pressure is now MIN spec.
if that passes but not on the real vacuum hose that means the hose is or clogged or cracked , 100% sure.
ive seen my 91 vac hose turn to black slime, yea, turning back to crude oil I guess, nasty nasty sizuki hoses do that.
more later,,,,,
but this is it. mostly
