Pontiac Sunbird 2.0 liter engine
If the is on Parking or Neutral the engine keeps running.
When I put the car on Drive and inmediately press the gas pedal the engine runs,
but if the car isn't moving and left on drive"example Stoping at a red light" the engine turns off.
What can it be.

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
