Car Idle Problems

I drive a 2005 Dodge Neon SRT-4, my problem is when I first start the car whether it is early morning(6 or 7) or later morning (about 11). The car starts fine, but after a couple seconds of just idling the engine starts to dye out. I have to keep giving it gas so that the car doesn't die out. I do this for about a minute, and once I leave my driveway the car is fine. It doesn't die out at the lights or sound like it's going to. What should I do? Or what is the cause of this problem? I also just replaced the PCV valve. Could they not have installed it properly?
