Default HELP Rough idle, Dies, NEED HELP FAST

So I take my truck to the mall today, 15 mi each way, runs and drives like it has been for the last year and a half- perfectly. Truck is a 2004 3.0 automatic with flowmaster exhaust, and nothing else.

So i just go to take it for a cruise, and i go to start it, and the key kind of slips, so i only get like a half a turn (not enough to start it). I then turn the key and it starts, but idles jumping from 500 to 1200, then dies after jumping for a bit. Its making really weird exhaust noises, and i have to keep it idling by being on the gas. If i rev it up, it stops at 3000. I cant seem to figure out what happened? didnt drive through any puddles, it just was parked, cooled off for 2 hours, and now this. Didnt touch anything, and now it just is doing this.

Ideas? Thanks

----------

Also, no check engine light. Just seems like its starving. Fuel? Fuel Filter?

Check the idle air control. I was just playing around a while back and unplugged mine and it was familiar to that. Just and idea

It will be on the intake on the throttle body. Looks like a little tube with a wire plugged into it.

Okay, figured out the problem! underneath the IAC there is a male air line that looks like it lost a hose, so i plugged it up with my thumb and it idled like new. Can someone with a 2004 ford ranger 3.0 or whatever IAC goes with that post a pic of under their IAC showing if its a hose or just a plug? thanks!

Bam! had a feeling it had to do with air, sounds all too alike. Glad you figured it out but i have a 4.0 ohv so i probably can't help you anymore. Good luck
