Hello - most likely, the idle air control valve is a bit gummed up and is sticking ever so slightly when it becomes the key control at a stop light. Cleaning or replacing it should resolve the "stoplight stumble."
I would recommend having the idle control valve replaced by a certified mechanic, such as one from YourMechanic, who can come to your location to get your car back in working order.
