Question about 2000 Ford Windstar

1 Answer

Engine starts but stalls, misfires intermitenly while driving.

Engine starts normal but dies out. The way to keep it going is to keep my foot on the acellerator and evintually it will stay runnig. after about 5 minutes the engine will die as if out of gas,but will start easily again.

I get 2 codes,p1132, and p1152 described as ( manufacturer control,air fuel metering) my service manual does not show these codes.I don't know what to look for.Can anybody help?

    Thank you for your sugestion.I did as you adviced and had no change in the symptoms,"BUT' the engine diagnostic codes did change. I now have code p1121.I also checked the specs for the IAC valve and it all checks out.( internally the valve was not sludged up very much

    thanks

    thank you for your guidance

    I went ahead and replaced the TPS and still got the P1121 code

    back.So then I got the Mass Air Sensor and that took care of the problem completely.

    apparantly this sensor must have been going bad because I use to have an intemitten problem of engine hesitating while cruising every so often and then it would go away.

    the engine now rus strong and is responsive on acceleration thanks again for your very good advice.

    my 2000 windstar idles 1800 then slowly idles down after 2 min. Then it misfires at idle and cruising.

    My 2000 Windstar also starts, but then dies and cokes when cold, and only runs good when running hot after 15 minutes.

Try looking at the idle/air control valve - Look around where the gas cables attach to the engine. remove the wires and then unbolt the unit from the engine. The control valve has a spring valve that you can clean with intake cleaner. re-install the valve and drive to warm up the vehicle. After 20 minutes the vehicle should Idle. If not clear all codes and relist them here - hope tthis helps

    First Code 1132 and 1152 are O@ codes showing that the vehicle is flooding



    P1121 Throttle Position (TP) Sensor Circuit Intermittent High Voltage

    If your scanner can show live data - view the TPS volt or TPS % reading with the engine off. the voltage reading should go from 0-1 as you press the gas to the floor.



    Check for any air leaks from the Mass Air Flow Sensor to the TPS Sensor and any other air leaks



    I would check the TPS wiring and possible change TPS sensor



    Note that Mass air flow sensors could also cause the problem and are $$$ to change. So I would change the TPS (20-25 bucks) first

I have a 90 geo prizm I have changed the plugs ignition control module fuel pump and fuel filter the car runs for a few minutes till at normal temp then shuts down when put it in gear any suggestions


wow , year, body name Prizm stated, Prizm is a TOY corolla.
but not the engine, or trans.
my wild guess this is the TOY 4aFE engine. 1990
i have 50 guesses for you, would you like me to toss dice and spit one out? or would you like to try real diagnosis.?
your call.
using real tools, lacking tools, its impossible to do this.

sorry. EFI systems and ENGINES are complex with huge numbers of failures, possible.

sounds like an auto trans there, shifting from Park to drive..
Best is to say DRIVE,
and when you do that a huge load is put on the engine.
and if its stalls its cause by 1 of 2 reasons.
idle controls dead;
or engine is weak.
so if you use the fast right foot trick you lean which it is.
is engine rpm at spec, hot ?
is engine rpm at 800 or more in park.
when you shift to drive, the rpm most hold at 800.
if not the engine is weak for sure if the fast right foot cant make car move.
if the trick above works, i can drive using the fast foot trick, then we do idle speed controls tests.
if not (its misfire, caused weak engine)
the engine is weak, top reason misfire or under injected.
under injected is lean and bogging engine, and stalls.
the 50 other causes. starts now. or up to 10 more tests.


starts ok.
idle cold ok, no misfiring? or engine shaking
can you drive it dead cold???????????????
then are you saying only the hot engine , shifted to drive
causes a stall but not driving a cold engine>?

if all that is true, then use the hot right foot, happy foot.
you foot can in fact bypass the idle controls of all EFI engines made (gas).
This trick adds air and the ECU adds fuel matching your added air.
see how this magic works.?
so does it work. this trick.? i can drive now it a happy right toe?
THE key answer, to diagnosis.

and if you hear /feel or see misfire, that too is key and no blind net bunny can see this.
it must be seen and reported.
spark plugs gaped to spec>/? not guessing?
new spark plug wires, on a car this old the original are all DOA.
compression at 150PSI or more , at sea-level to 1000'feet.
if not , say so, and the readings as WOT. (open the throttle to do compression tests are its all just a wasted effort)
cap and rotor new, (26year old parts here are junk)


also battery voltage need to be 13.3v to 15vdc running.
if not ?and the alternator is dead, the voltage drops and EFI stalls the engine, so we always check system main voltage on all cars the run bad, and fuses.

we also check fuel pressure ! on all engine that flood or bog.
and the flash codes, (magic 1990 jumper clip flash codes)
ask.

Why does my jeep turn off if I don't toggle the overdrive switch enough?


it stalls with foot in the throttle...... really.? try to say what you and car are doing at the od switch flips.. sure moving fast.
but doing what, up hill down, flat, acceleration, decel, or coasting?

ok, this can be real easy.
engine tuned up is 99%
ever heard of scan tool.
connect it, and log data (or person 2 watches) and log DTC and streaming data?
if the Magic relay called ASD drops the the engine stalls (this is its purpose) and if it did the SCAN TOOL tells you why it did.
every time...
asd class 101.:
http://www.fixkick.com/Jeeps/ASD.html

is transmission stuck in 3rd gear, limphome.??
the trans mission will not stall a car. 99%
that is because the clutch has a stall speed.
and slips greatly at idle, say 800rpm is hot idle , so if say the trans solid locked into top gear. and you came NEAR a stop sign, coasting... and braking.. say.....
and as rpm dropped, the clutch will slip and no trans ever stalls the engine.99% unless the engine is super weak and misfiring hard.
or ASD DROPs !
that is why we scan to see ALL ERRORS> engine and trans.
see?

Engine dies if I dont keep foot on the gas The Garage. ... foot on the gas the RPMs immediately drop to zero and the whole car dies. ... In that case the throttle body just had enough gunk on it that it was ..... My battery died two days ago and I got a boost but it stalled immediately after taking my foot off the gas.

STARTS BUT WON'T STAY RUNNING


Could be something as simple as a dirty fuel filter.
Get a can of quick start at the store and have someone start it up, when it wants to die squirt a shot into the intake ... if it runs again for a bit you have a fuel delivery issue. Check the fuel pressure to see if the pump is functioning properly.

I have a 98 isuzu rodeo and it wont stay running unless I keep my foot on the gas. The check engine light isnt on so I have no clue what to do, can anyone give me some suggestions please?


hot or cold engine,or both????????????????????
sure...
the ECU works OVERTIME; hard, to keep the engine running.
this is done by the action of the ISC valve.
so can you keep it running with a fast right foot??????????
a real mech needs to drive car.
does it have full power on hills?
is the tune up service done, the 60kmile repeats and needs to be done.
the ECU can not keep idle right on any engine that runs like crappppppp.

1: all fuses good.
2: engine never warms to normal 180F+ temp and hold???
3: not tuned up.
4: engine misfiring.
5: engine flooding.
6: engine starving for fuel.
7: OMG, the ISC wires fell off, (inspections do work on old cars)

there are simple tests. for each case.
one more #8. EFI system lost 12vdc power. stalls.
12.6vdc not running, 13.3v -15v running.

1996 jeep wont stay started and oil pressure gauge goes up and down


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 .
