Rpm - Engine stalls

engine stalls when parked? or driving fast>? not told. engine stall is 0 RPM engine as in dead.
and restarts easy.
does engine STALL going from park to DRIVE or REVERSE.
that is a super rare even so rare I think it is just coincidence.
the cars cab heater, blower fan turned on low to high? at the dash knob HVAC.
or at engine fans, Radiator rear or font, fan, condenser HVAC.

first off the blower fan is fused, say about 20amps, and is never going to overload the battery or 100amp alternator ever, not possible. nor the GOOD engine,
wiring hacked yes. my answers or for NOt HACKED CARS OEM STOCK.

answer 2;
engine is very sick and weak, and RPM is too low say 600 not 800 or more.
so any load on the engine stall is it, blower or going in to drive.
in drive, foot on brake RPM is 800 hot or 1500 cold. not 500 ever.
those need to be known first.
or get the car services for SURE if you can demonstrate he failures. to them.
this answer if for any engine on the hair line cusp of stalling before it does stall.

see?

no engine size told.
well there are like vast causes of this
my engine starts but stalls.
even parked in a drive way , transmission in pARK?
The macro causes are 3. (100 yeas same gas/petrol) rules
bad spark
bad fueling (even bad fuel)
bad engine (cam belt slipped) this fail trumps above.
a tech tests them all in order.(based on age, and miles) saves time.
no miles on car stated 100k 200k, 300k miles or more?
when was the last tune up (filters all, spark and belts)
not told. and matters huge.
does it fail cold and hot engine both, or can never get it hot
hot = means normal engine temp, 180f to 200f
is RPM started up, cold 1500RPM or less (or happens too fast to tell)
does engine die just as you shift to DRIVE.?
failures parked are the most easy to find, (moving fast failures hard)
tell more and get more, tell all things the engine does, in all modes of use. AND WHEN AND HOW LONG IT TOOK TO FAIL.
or hot engines turned off will not staRT (BUT CRANKS FAST)?
THERE IS A STORY HERE BEGGING TO COME OUT BUT DID NOT.

THE MICRO LIST IF CAUSES ARE HUGE.
EVEN a bad wire vast.

how soon after it starts does it stall,
1second 1 hour ? what, ?
some engines fail hot soaked, starts cold, but never hot

when STALLS only driving , any time , or just as I come to stop it stalls. or stalls parked only. my guess parked only.
which engine is there?
3.1L
4.0L
4.7L ?
what transmission, what A/T trans, 42rle or ?
mileage comp. like mine, it's useless. forget that. but dead battery reset that, and is of no matter.
questions are plenty on all cases: (cars are complex!)
the engine stalls.? sure.
in to gear means , Drive and Reverse right?
when you do that the PCM adds more air via the ISC idle speed control valve. and just my do that. and is good sign.

1. besides stalling, does engine and trans work great , driving, like fast /slow, , hot/cold engine, , up hills too, fast?
2. is the CEL lamp in dash on key on and off running.?
3. did you check all fuses.
4. what is miles on engine.
5. when did it run perfect last, 1 week ago, 1year, 10 years?
6. ever get and engine tune up this decade? spark parts and filters?
7. is the ASD relay dropping out just before the stall>?
8. is engine rpm below 800 RPM before the stall? hot engine.
9. does engine reach and old full engine temp, 180F or more?
10. use a scan tool and see all DTC errors yet, dont skip this.

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

which engine,? the have up to 3 choices.
rih?
what are the full symptoms,
did you do the full listed 60k mile tune up on car?
sparkplugs,wire, cap rotor/filters? no engine runs right with bad spark
unless it's a diesel.
starts good
runs good or bad hot or cold engine
idle at 800 RPM hot?
stalls> when hot and cold engine
lost of power
bogging
misfire,
learchs>

only stalls , but runs perfect even up hills, at wide open throttle.
fresh gas, or 1 year old?fuel.
can your fast right foot , save the stall, and easily?

ok stalls 101.
1; lost 12vdc to EFI system.
2: lost engine compression.
3: lost spark.
4: lost fueling or floods
there is a simple test for each.
do you want more guesses, or how to do tests.
can do both, but my guessing fails 99 /100 times.

tune it up
do the right foot test. those are always first. on stalls.
always.

hot or cold engine , or both.?
the oil pressure will be in direct ratio to engine rpm. slow low, fast high
due to the oil pump connection to engine crankshaft.

stalls.: can be caused by 50 things, or just 4 in physics.
the EGR valve (if you have one, no engine stated)
can stick open and stall any engine, and in fact LOVES to. clean it.
1: list 12vdc to EFI. (spark and fuel brain) dash lights dim?
2: lost compression hot, ? compression tests.
3: lost spark, do spark tests. and timing, checks.
4: bad fueling, too much if floods, and misfires and stalls.
too little fuel, it starves and dies.

the 1 free test, is can you save the stall with a fast right foot.

we do the tests. avoiding those 50 guesses....
each tests are simple and the tools dirt cheap .

the automatic transmission creeps? is that it?
that means the (brakes are dead) or the engine RPM is too fast.
if engine is cold (was it) the RPM can be and will be very high and will creep. so is it cold, the engine , and how cold, was it at time of creep
and what was the engine RPM.

or does e ofline mean off line or really means stalls.
as in, my engine when off line, like printer. or ?
wild guess there.

this is simple, all A./T have a clutch that has a stall speed
if you exceed that, RPM it does creep, that is how the a/T fluid clutch works. That is why say , when you idle a 800 RPM it dont creep
then you advance the throttle (engine rpm rises) there is a point
that car starts to move, this is the stall speed, threshold.
all normal.
this is why the operators guide has you start the engine brakes on
and trans in park then while holding the brake , you shift to drive
and prevent creeping,,,,,

id go for chicken feet and blood and voodoo , sessions.....loL

first off, i see an illegal fast idle ,
and all A/T trannys do that, when the engine rpm fraks up.
to move car, due to the stall speed rules of the clutch torque converter (aka ,the fluid clutch) wiki clutch stall speed.

that A/T weakness, is why folks run over kids. (the lame excuse)
starting a car with foot off the brake is , folly, thus the lock all outs called park lock features.

i can not follow your sequence of events.so will ask questions.
1: I start the engine, its don't want to but does. (ever tune it up?)

2: Does the CHECK engine lamp go out (CEL/SES)? running.
for sure, if the engines stalls many lights will glow in the cluster but that is normal, see? for any stall.!
The Charge light comes on anytime the Alternator goes dead
or hits near 0 RPM (stalled)
so are you saying at 3000 rpm, the charge lamp came on.
/??????
battery lamp is not battery, its really a Charge lamp.
the op guide states that too.
on my car I have a battery gauge too, and shows VOLTS.
at idle its 14v. its 14v at all rpm. if less, say so.
I have 2004. GV. with full manuals. even factory FSM. ++++++

ok , in drive, no acceleration, are you saying ,
1: im in A/T drive.
2: the engine is idling at 800 RPM hot or near 1500 cold
3000 is wrong, dead wrong, you in ALASKA, state location(gen)

i increase the RPM with my right foot and the car don't move
in DRIVE
as RPM rises above 1500 RPM, you do have a tacho , i see that.
if it does not move with hgher RPMs, the trans is bad or its TCM is bad.
on your car the TCM is hidden deep inside the PCM. back in 1997.

the PCM runs the engine and tranny today.
if something lies to the TCM/PCM the tranny will not go into drive.
on newer 96+ cars, you see the check engine lamp glow.
running (not stalled, stalling this CEL glows all the time)
but running, the CEL glowing means Faults found, scan me,. please.
eg:
so you scan it, and find DTC's stored (many?) eg.... in english...
the transmission selector switch is bad. or worse.
not using a scan tool ,means ($7 cost) means you miss all the facts. hard cold real facts.
the ECU can not shift any car with a bad selector switch.
so throws the DTC error.
it can be even be a loose selector cable, cave man simple.

recap.
does the CEL lamp stay out running at all times.
no, ? then scan it.
do not post car problems with stored, or pending DTCs on any car newer than 1995. or its just wild guessing.. mostly.

you could have an air pocket in the cooling system that has to be burped. With a cold engine, park uphill and leave the radiator cap loose. Fill radiator and coolant reservoir. Start engine with cap loose and run at 1500 rpm until temp gauge reads normal. Feel if top radiator return hose from engine to radiator is hot. If yes, coolant is flowing and thermostat is open. If cold, thermostat is not staying closed until engine is hot.

report results.
