2000 Sable DOHC, rough 500 rpm idle, stalling, no codes

Weird gremlin in my 2000 Sable, Duratec yesterday. Was fine all day, fired it up after leaving one location - had been sitting maybe 40 minutes - and it wouldn't idle for beans. Stuck around 500 rpm, rough, and stalling.

Tried shutting down and restarting, same thing.

Got on the road, it accelerated and ran fine until I came to a stop, then the same 500 rpm idle/verge of stalling deal. Figured I'd get it home (30 minute drive) and have a look.

15 minutes into the drive the problem just disappeared and it has been fine since. Had a similar issue (identical, actually) about a year ago and it disappeared then as well.

No codes displayed.

Car as 129K on the clock, plugs/pcv/MAF were replaced about 105K. Thinking maybe IAC?

Very odd that I didn't get a code even though it stalled more than once.

It's very possible that the IAC is hanging up. They don't always pop a code. You could try cleaning it.

I'll probably pull it apart this weekend and clean it up, though it is relatively cheap so I might just replace it.
