Clean your IAC valve good first, it's an easy thing to do that night fix the problem. If that doesn't work I would try getting some mass air flow cleaner and cleaning the MAF and then the throttle body while you are at it. Those will be the easiest places to start.

If you do clean it make sure your order a new gasket first. I did this when I dd my 2000 gt and ended up having it leak for a week until the local autozone got a new one in

grab a can of MAF cleaner and clean the MAF, and IAC...then also clean down the TB while you're at it. usually takes care of 99% of idle issues like that

Wouldn't vacuum or stuck throttle cable cause this too. Jus wondering since the throttle climbs then when it drops it goes to the bottom if the rpm band close to stalling.

replace your IAC... i got a one off e-bay for 30 dollars... the brand is standard, and if its not the problem its better then an 80 dollar motorcraft. if that fixes the problem, wait six months and buy a better brand, then you'll have the 30 dollar one for diagnosing.

don't clean it, it only oxidizes the inside of the valve and strains the electric motor more resulting in an even more tired valve. you won't throw a code till it completely dies.

when you replace that reset your KAM.
