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.
