clogged injectors. due to bad fuel? seems to be it.?
try Chevron Techron additive (if you can find it, it's loaded with powerful Benzene) many additives are useless. oil, or Stoddard solvents or other oddities.. (lots of bad ones, either useless or harmful)
if fuel pressure is good. (spec) and varies by Altitude, (the reason for spec, range is that , and mfg variances)
RPM with tps (HOT) cant hold a steady 2000 RPM BTW
do you mean WOT? or HOT? i want both, HOT wide open throttle up hills, in 3rd gear, just and avg. hill not extreme. (no San Francisco, dig?)
the engine puts out about 95 HP at flywheel. MPI engine.
explain what WOT does. on hills, this is full engine load. 100% 95HP.
weak.
misfires
bogs.
surges.
hesitates and catches up to full power?
?????????????
im no Additive guy, not at all but if , no pressure gauge, what else is there????
run a bottle of techron through it and pray,

the FSM is clear.

30-37psi, (This range is for altitude unknown) as you rise in ALT. the fuel pressure drops. at rail.
Vitara 16v G16B 5door JLX -94 5 speed. MPI with 4 dirty injectors
if you did the injector balance tests and it failed ,they are dirty
if by wild chance, rare , all 4 are equally dirty (they have 10micron screens inside) then the balance passes but are still cogged. can be.
the balance test (tricky) show that each injector flows the same.
its speed of leak down test.(injector activated)
also leaking injectors are possible, with bad fuel.
can't do MPI work with out a pressure gauge and a NOID lamp, ($1)
you can see the factory book there, using the guage at the fuel rail. (takes special fitting , seen on my pump test page , sold at summit racing, for $10
and can be done at the filter, but the balance test would be a horror there.
I add a scharader valve to all cars. seen with none. it's first thing i do.
here is what some of what ive done and others.

but at least this, part here. is the top way to get progress. with this one part you can fit up what ever you need.

NPT, national pipe thread. (tapered USA spec.)
note how the rail thread size is clearly stated there.. 14mm x 1.5Pitch.
one more fact
when you go WOT., W.O.T , wide open throttle.
the plenum goes to full (near) atmospheric pressure, the PFreg increases fuel pressure, by about 6 PSI.
if not, the engine BOGS HARD, starves for fuel.
this is how it works.
this is why we do all 6 pump tests, all MPI balance test. and 3 tests on the FPREG. or its all a crap shoot.
