My car runs good when it's cold but stalls once it warms up? ... In this situation, you can usually re-start the engine once it has hada chance to cool back ... it'll fill-up and exits fuel right up and out the vent tube which dumps it down the middle of ...
When the engine warms up the engine computer goes into closed loop mode and relies primarily on the O2 sensors and the MAF sensor to calculate the correct fuel to air mixture - if one of the O2 sensors is fouled or the MAF sensor is not working properly, this can cause the problem.
Given the age of the car, I would also check the idle air control (IAC) and channels, the EGR valve and the throttle body for carbon buildup.
you know what that sounds like it may be.... believe it or not check your trans fluid (car running WARM and in park ) make sure that the fluid is red almost pink like not dark red. Also why not try and change out the spark plugs and air cleaner!
Check your 91 Accord's ignition coil. The coil goes bad at apprx. 150k miles and cause the car to run rough, hard to start(long cranking time) in the morning, stall after the vehicle has warmed up, cut out while driving and backfire horribly when accelerating from a standstill.
I need to get a clear mental picture of what exactly is happening.
With this said, you stated that the car "runs fine" until warmed up.
Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?
