Re: Also, please tell us this car's mileage?
If "little mileage" includes a cold start followed by immediate shutdown, it's possible the plugs are fouled. I've done that moving the car out into the driveway to wash it, and then back into the garage.
Usually, though, you'll have alot of trouble starting the engine. If you suspect that, try driving it a good long distance, like on the freeway for an hour. If that doesn't help, try replacing the plugs.
I think fouled plugs is actually pretty unlikely, because it's less of a problem with modern fuel injected engines, but it's easy and inexpensive to rule out.
