Hey tom its a 1990 pontiact transport van and it starts out fine and as soon as the vehicle warms up it will stall it will start back up but when you put it in gear from park it stall again until cool?
Look for a vacuum leak.
Why would it stall or almost stall in Reverse but not in Drive? How long since it's received a tune-up and thorough check-up? How is the compression?
The compressor sounds like it is burned out. When the AC is put on, the compressor starts to cycle driven by either a belt or serpentine belt. If it is malfunctioning it will actually stall the motor. Thanks for your response... How ever my compressor in working perfectly fine...I already solved my problem... I just clean the IAC Valve terminals and when I try to start my car and turn the A/C on, wala...! My car Stall no more... hope this will help others.... thanks guys... till next time..
check the fuel pump
have you checked the spark plugs and wires? if not try replacing those... my 95 eagle talon did about what yours is and I just replaced the plugs and wires and it runs like a top (with over 200,000mi on it!)
Check your IAC valve. Could be bad temp gauge. Could be idling too low.
Coolant temperature sensor. 20 bucks or so
One common problems is a plugged catalytic converter, if the engine starts fine and then starts to stall or feel like it does not have any power after running for a while it could be the catalytic converter.. the engine starts loosing power because the exhaust has nowhere to go (the catalytic converter is partially or totally plugged) Compression starts to go down causing the engine to stall or die. If you leave the car alone for a while the pressure in the engine goes out slowly thru the catalytic converter leaving the car ready to start again for a few minutes but it will shut down again.
If the check engine light is on...might be a dirty EGR valve.
I would check clutch plate, if faulty renew, the clutch might need adjusting.
It is idling to low, it may be in need of a tune up.
if you got an automatic depending on what gear it is you may need a 2800 or 3500 rpm stall in your torque converter call a transmission shop if that's it they will help you
is the exhaust pipe pluged causing back pressure ?
my 97 aspire did this had it checked out and all tha was wrong was my timing was off and had to be adjusted
timing chain or distributer --or gypsies, gremlins etc.......
I suspect a bad distributor. Honda distributors have been known to fail.
maybe fuel injectors?
I have a 95 Pathfinder and had a similar issue. The engine would cut out when coming to a stop or making a turn but was fine when giving it gas. I had a fuel system flush done (but not a new fuel filter) and it has been fine since.
there are exterior stick on lights that will do fine in that moisture
your crank angle sensor playing up.
Check fuel pressure.
I can start my car fine, drive it for awhile, then its like after it gets warm it seems to stall, and shut off, then after tryin to restart a few times that battery acts as if its dead. I will sit there and wait for about 20-30 minutes and it will start right up like nothing happened, just to do it all over again. Can you tell me what the problem is?
