Engine starts and idles high

I have an '06 Taurus 3.0L. When I come to a stop the engine idle sticks at 1100-1400 rpm then after 3-10 seconds will abruptly drop to normal idle 600-700 rpm. On rare occasions when it drops the engine will stall. The sticking high idle seems to be most consistent/repeatable during cooler/cold weather but it will also do it during warm weather just not as frequently. It happens when the engine is at cold and hot operating temperature.

I have had it to the Ford dealer twice for this and they said there are no fault codes that come up and it doesn't happen long enough for them to diagnose.
PLEASE HELP!

Thank you for this post I had this problem it fixed it perfectly :0) I love this site.

Why is my car idling high

I have had this problem corrected in the past and I can't remember the name of the part I need, When I start the vehicle when its cold it will race to about 2500 rpm, I believe its idle speed control sensor or something like it but the parts store does not list it like that they have a throttle position sensor or idle air control valve, I just can't afford to be experimenting because I have throat cancer and on a very limited budget so whatever help you could give would be appreciated

Thanks for the guides I had this problem and fixed it for almost nothing

I have a 2001 ford taurus that idles high when I first start it but after driving it and coming to a stop at an stop light or sign it stalls on me. I dont know anything about cars but where it shows my rpm it goes at least 2lines under the #1 then my car shuts off. It also I guess bucks when I have driven it and sounds like it reeving up and down moving the car foward and backward (I GUESS THATS WHAT YOU CALL BUCKING, LOL) Idk im just lost. I was told by a mechanic friend of my brother that I might need a fuel pump. I just wanna get a second opinion before I start giving out money I dont really have. So could someone please help me and I hope that was enough info. Thank you.

At start up engine rev's to about 2grand then it will step down after a min or so to about 1grand, unless I hit the throttle that will bring it down to 600. Once at 600 throttle response is normal. TPS?

I don't let my car run that long. If it goes to reving I cut my car off. Should I keep it running? The gas pedal don't seem to work when the car is revving

Just started car it had a slight putter, gave it some gas and it seemed okay thought maybe bad gas. Drove car to the store, barely half mile. I barely made it through the drive through, it suddenly went back into a sputter. The engine seemed like it was going to quit. I made it back home and this is where it got really weird, as I was trying to put the car into park, in neutral the car went up to 2.5 rpm's, the car was revving up. I don't know why but I try to put the car back into gear to get it to stop. I put it back into drive and thought it was going to throw me into the side walk. It did drop the engine back down to 1 rpm. Back to neutral it tried to rev back up, so I shut the car off in neutral. Has anyone heard of this problem?

I have a 1996 Ford Taurus station wagon. My car idles high and the tac goes between 1.5 and 2. What would cause this problem and how can it be fixed?

My idle should be around 1 ond the tachomadtor, but it's been sticking at about 2.5 and won't idle down. Usually this happens after driving for a while at 65 on the highway. Sometimes when I stop and restart, it will come back down to normal but not always. The check engine light has been coming on intimately and stays on about 5 seconds and then turns off again. Is this the idle control box? If so how do I change it?
