Sounds like the computer is not being told the fuel air mixture. Locate the coolant temp switch, usually located at the thermostat housing. should have 2 or 3 pins. try unplugging it and see if it changes the symptom. You can also check the switch with a multi-meter when the reading will change depending on the temp

could be a few things the start up could be the idle air control sensor (my first thought), the coolant temp sensor for the computer might be a secondary thought for the engine being cold if the computer thinks its warm. that would be the first 2 places i would start without a check engine light or code to reference

Engine will not idle until warm. then it is just fine


This is normal, as long as the rpm's are not above 2000, this is to heat the engine to it's operating temperature quickly. Once the engine is warm, the rpm's will drop to 600-800RPM.

High idle speed when the engine is cold


The high idle speed at start up is normal. As the engine temperature increases, the engine idle should kick down automatically. Insofar as the emissions results, if there were a problem, the check engine light should be on. If it is, take the car to an autoparts store and have the fault codes read. Most parts stores will perform the scan for free. If the check engine light is not on, and the idle question was all you were worried about, you are good to go! Hope this helped and best wishes.

4 cyl Engine starts and idles ok...give it throttle and it dies


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?
