Won't Idle! please help

[sp3cialed]

Well as some of you know, i'm trying to sell my car. i had a guy look at it today and the car couldnt hold idle... It's only done it one other time about a month ago, but i revved it right up and it held at 800rpms. This time no matter how much i rev it, or hold the revs till engine temp is hot, it won't idle. no CEL. Gonna bring it in in the morning (this may be a fun drive...) but can anobody help in the mean time. I'm guessing the IAC after searching... thats the same thing as air bypass valve? thanks

oh, the cars got 160k+ timing belts been done. not sure about plugs, wires, and fuel filter. when it idles, just earlier today, idles like a champ. sits at 800 no stuttering or anything.

MAF? sorry I'm doing tons of searches looking for an answer... haha

I believe its the IAC my solara did that when i bought it but we replaced it..and now it idles great at 800. if you ref it a while and let it warm up it should be fine.

I had that problem a few months ago. It would start and die immediately. I cleaned the IAC and I haven't had it since.
