There are way too many possibilities that could cause this problem and so difficult just to guess without being able to drive your car and experience the problem first hand and or do some basic diagnostic tests. The engine may stall due to a problem in the idle control circuit (modern cars have a motor controlled by the computer to stabilize and control the idle). Vacuum leaks, break down of the ignition or fuel supply to the engine can also cause the engine not ot idle.Your car has On Board Diagnostics Level 2 (OBD2) many scan tools are capable of reading live data from the many sensors on your engine and transmission by simply plugging in a scan tool (hand held computer) to a diagnostic port under the dash board of your car, this scan tool reads an amazing amount of information which is live sensor data without having to intrusively test each sensor individually (convenient and time saving) The tool is only as good as the person interpreting the data and not every scan tool has the full capability to work on every particular manufacturer of car.
I have an OBDI scanner that does not fit on the car plug, the OBDII fits but it does not show any code. I can't find a scanner to check my car (1994 Buick Le Sabre).
