Your car stalls at stop light is caused by either fuel or air hesitations when the injectors air/fuel mixtures are out of proportion. You can also put a pint of Gas Treatment in your gas tank to see if it can do any help.
Or, a defective coolant sensor may be telling the PCM the engine is colder (or warmer) than it really is. Any of these conditions can upset the fuel calibration of the engine and cause a stalling problem. Intermittent stalling can also be caused by a bad idle air bypass motor or a idle speed control motor. If these devices fail to provide the correct idle speed, the engine may die. Sometimes the fault is in the PCM or the inputs to the PCM.
