So, I've searched and could not find anything similar to my problem. When I start the car it idles up to 1500 for a second then drops down and dies. If I give it a little bit of gas it will when it starts to drop down, it will level off at 900 and not die. Any idea why this was happening.

You might want to clean your throttle body. Check your IAC valve and TPS.

have you checked your entire intake system? your throttle body could be all gunked up. but yeah, kinda sounds like a fuel issue. i would check the fuel pump.

I was thinking it was the fuel pump, every now and then when I turn the key to the run position, the fuel pump sounds a little off.
