Wicked idle issue

So just recently I've started to develop a severe idle issue. When I start the car I have to give it gas in order for it to stay running. As well my rpms drop really fast on decel, and if I let it idle for a a minute or two they will drop alot and it will just die. When it does idle right, which is around 800-900 it's still shaky. The car has heads, cam intake. I do hear a loud whistle which I hear is typical of a Trickflow intake. Please help guys, this is annoying.(this is on another stand help site btw)

Thanks guys, I got it after sitting outside for a while thinking. It's a foxbody style intake swap, so it has a few of the connectors spliced for IAC and tps. Well, one of the wires for my IAC had come lose. Problem solved, and yes, I have 24's waiting to go in. Just wanting to be sure everything else wants to cooperate before I start throwing new parts at it.
