Power loss while gentle throttle

[fixkick]

94 G16B. WHICH TRANSMISSION?? 5sp?

94 G16B.
OK, Well after many hours I have now come up to this.
My topic feels a bit wierd...
More like; car will bog under light steady throttle

EGR:
*stall test OK. Is there a point of doing the "live test"? (the live tests , then prove, the EGR works moving, but just look for DTC 51, if present live fails.)
*Cleaned

FPreg: I have no tools for this, neither any mechanic store nearby...have to order.. harbor FRIGHT tool , has it for $20 and the adapter FITS !
*But no fuel leak to vakuum hose
*No change to RPM when pinching return hose...
(no and effect is normal, but on pinching, with hand gunning engine, that would make AFR go lean)
pinching the hose, locks in the vacuum at PFR, (id diaphram is good and not cracked) so nothing changes. but if you gun engine like that.
the plenum goes to near full atmospheric pressure. this will be lean because the pressure most rise,(fuel) as you go to or near WOT.


TPS: Calibrated as accurate I can, position and measured in (correct) range, idle to wot
* When plugged in I cant hold a stable 2000 RPM, drops about 500-900rpm and up again.* HOT OR COLD?
*unplugged no idle (1000rpm) BUT I can hold it Stable at 2000 RPM
running in limphome is of no use at all in diagnosis. nearly so... and doing so , kills to sensors at once, idle switch and throttle angle. bad that is.


Cooling system:
*No Smoke from tailpipe, when hot
*Gauge indicates just below mid in temp scale.
*Sometimes the expansion tank is full to the top (dry RAD top as I can see), sometimes almost empty and RAD full..?

Vacuum: I haven't found any Vacuum leaks... and no clogged up hoses...yet.

RPM:
*Cold start around 1800 for a couple of min's
*Hot around 800 sometimes down to 600 and no misfire och bogging (600 is wrong, this means the ECU sent a command (not limphome) to the ISC and it failed to open or AFR is way too lean) the trouble is , no scan tool or scope to check AFR.
*When moving, clutch pressed around 1500 RPM
*Pinching ISC hose drops to 400 RPM (so ISC is flowing hot,good)
* Car feels heavy/powerless when going on low RPM on high gears, (read gear 3 on 3500 RPM, doesn't get full power until 4500rpm (normal?) no.
that makes it hard to change gears smoothly as I have to meet throttle/clutch for a quite long time, since it lacks of power...

MAF: Cleaned, and measured voltage/resistance OK
*Car will not be able to drive unplugged (again limphome is not to be used to test cars, doing this burns up CAT fast)

Oil: No signs of contamination from coolant,dust etc. Stabile level.

ISC:
*Seems to work, pinching hose rpm drops as said.
*cleaned
IAC:
* I plugged the throttle to IAC hole, no change HOT (VERY GOOD, no bad IAC) !!!
* I haven't checked or cleaned it...

Regarding injector cables its only the outer shell thats dirty.
there might be some symptoms/checks I forgot..

I just cant solve this riddle

its lean,, with no scan tool we can do this
1: all inputs to ECU good.
2: there for, fuel pressure is low,. or injectors clogged

i think its lean. and i GUESS its lean , at WO?T, you HAVE LOW POWER in 3rd gear up hills.
if yes, and MAF test Passes, then bad fuel pressure, or clogged injectors.

the ECU can not inject correctly, with out of spec, fuel pressure.
20 PSI is no good.
did this car have bad gas on one point ?????

please type away, this is a car fix site , not a Grammar Nazi test zone. or any thing like it, even use wrong names for parts we can sort all that.
i wish my spanish was as good as your english !
welcome and enjoy and ask any questions you what.

im sure now, there is no HARBOR FREIGHT STORE THERE.
The hose that fits has a 6mm thread on the end. that fits the filter.
fuel.
