I'd be more worried about why you parked your car and left it running. Maybe you should try AA.
Yeah, that is definitely a concern. As for the car, unless it overheated, there's no cause for concern.
What I would do is add "Chevron Techron Concentrate Plus Fuel System Cleaner" to help clean out injectors, plugs and carbon in engine from the long period of engine idling... then take the car out for a blast on the highway for a 1/2 or more.
