Question: Why is my RPM fluctuating if my car is idle or stopped at a red light?

I just started having this problem yesterday my car was driving fine sunday night went into a friends house for 20 mins and came back out and my car wouldnt turn on..thinking right away it might be a battery problem i got a new battery and it seems to work fine except for when im in idle my car's RPM fluctuates not above 1000 but hovers between 500 and 800 and seems like the car just wants to shut off. Im actually concerned because winter is coming and if it dies on my in the middle of the road in winter im gonna fight some piece of metal..any thoughts or help on this would be greatly appreciated
