what is rpm hot idle, that is all that matters , step 1.
what is the number, ?
best is to do simple easy tests and replace parts $$$ last.
if the FPR looks old it is .....
good the ISC pinched. shows there is no huge plenum air leaks, nice test.
are you telling me you don't have a dash tachometer????, (2WD) many dont , most done. lacking the 4wd option with free tacho cluster.
my 4door 2wd had one. but was newer. sold to my mail man.....
If the idle is out of control there are simple reasons why ! (isc not jammed) too lean or too rich (misfires) or idle switch bad.
as with all cars, engines with low power. (lots of reasons)
why does stall test passing with 2000 rpm. seems like engine is very strong for this high RPM stalled. (but that is at 0 mph)
looks like its loosing power only on hills? and only driven fast.
A/T shifting is complex.
a tech would have to drive the car on the flat aggressively and then a hill to judge power.
my gut feeling is the A/T is 100% ok.
and lacks power on hills.
only.
just loss like, not 95hp but only have 60hp on hills. see? its not tranny slip. for sure.
it's lack of power. under certain conditions, at tech drives the snarf out car to learn that, and i cant.
the tech looks for lack of power at all speeds gears and loads.
and for misfiring and or clean linear bogging (like dragging a huge weight)
the trans is programmed to not up shift if the load/TPS angles are too large.
a fact.
if you had a real 1996+ car, we can read all that, on live scan, see TPS angle and load.
see maf output, etc. in fact all sensor data live.
on this car we cant. (unless you buy the Rhino tool)
low fuel pressure
FPR bad.
(im assuming engine timed right /compression over 150)
injector screens clogged.
fuel filter clogged
bad gas
maf last, but must work 100% at WOT or the power will never be 95hP nor will the trans ever shift right with a weak maf.
really what is wrong here, lack of 95HP on DEMAND.
1 hp per cubic inch displacement here.
when i hear idle speeds wrong (still not reported yet, by you where RPM IS HOT)
my head goes. why.?
and wonders, is it too lean. or too rich? why.???? i never ignore problems, they like to stack-up.
they also can be the cause of the next hard failure. that early warning.
why ignore this , clear symptom.
if and engine is lean, running, it can burn valves. or ping (flogging a lean engine can do that)
i never ignore those early warnings
are you sure this is 4speed
with OD lamp? (cluster lamp)
and OD switch? shift lever top.
and P/N tranny console switch??????
the 3speed, loves to smoke with the 3speed vacuum diaphram cracks.... 4sp has no such part.
some folks think TCC lockup is 4th gear, its not.
4th is a real gear and is aka. OD.
sorry for dumb questions, im blind here, and drivelines vary.
you saw the TCM with eye balls ,i think, so it's a 4speed.
white smoke, with ISC pinched is the PCV valve sucking oil, as the plenum vacuum goes to moon. ( 25inches HG,just before a stall or near stall, 400rpm)
or the worst case test for intake valve seals, at that horrific vacuum , at that moment.
