Starting Problems

[Darksied-X]

My SVX has had some starting problems since yesterday morning. The engine doesn't want to fire up, and when it does, it sputters for a few seconds and dies. Eventually it starts, but sputters for a few seconds before it starts to idle. Then I have to let it idle for a few minutes before I give it some gas, or it will die. It only does it after the car has been sitting for a while, like 4-5 hours. And the Check Engine light has been on since it started doing this. It's had trouble starting a couple of times since I've had it, but I'd just give it a little gas and it'd fire right up. And the engine light has come on before, but not for very long, so I just blew it off. Anyone have any ideas?
