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 ...
Likely, it is fuel contamination caused by use of ethanol blend fuels over time. I'd recommend replacing all fuel in the system with new (preferably non-ethanol fuel if available). If you must use ethanol blend fuel, add WATER REMOVER additive monthly.
Also, replace the fuel filter and check the operation of the fuel pressure regulator.
When the engine is still cold I back out of my driveway and when I shift the transmission to Drive the engine stalls as soon as I step on the gas. It does this repeatedly until the engine warms up. There is no check engine light.
Sounds like a cold start valve (which is actually an additional injector in the intake to assist in cold starting) If you can get it to your local prts store while the light is on they will read the codes for free and tell you what the car thinks is amiss.
check engine coolant temperature when it gets warmer, or at operating temperature, and verify that the temperature gauge is showing warmed up to operating temperature. If the coolant temperature sensor tells the computer the engine is cold it will over fuel and miss and the engine will die. When cooled down it will run fine until it warms up. Also could be coil if it starts missing after warmed up.
Replace the fuel filter. The new gasolines with ethanol tend to lloosen any crud in the gas tank, which then plugs the filter. When the engine stalls, the crud falls away, and it will run again until it plugs up again.
