So after trying a map sensor wack, an ECU reset and a cleaning of the IAC valve (which was pretty dirty)...I still had the oh so common idle stumble/near stall issue.

My next effort was going to be replacing the MAP sensor. My car would do the whole nearly stall when clutching in or most often when you would move up slightly in 1st gear and then clutch back in (in traffic situations etc).

Well yesterday I replaced my old engine air filter with a Napa Gold air filter (made by Wix). The old filter was the original, having 31k on it. To be honest it was REALLY dirty, basically solid black all around.

In all my driving yesterday and today, I have had not 1 stumble. Fluke? Could be I guess, but it's never gone so long without a hiccup. I was even poking the throttle a little bit while at stop lights.....as this would normally cause the near stall before. Nothing. Idling perfect at 900-1000.

I'll update this thread if in fact it stumbles again, though in searching the board it seems as if a couple other people have changed the air filter and received the same fix!

*knock on wood!*

Thanx! I was just about to start on my IAC to try to correct my stumble issue.

Well I'm still glad I did the IAC clean. It was very easy and took 15-20 minutes. The valve was pretty dirty and could have used it anyway, I'm sure.

The filter seems to have been the culprit. At least it seems so for now!

This picture makes it look better than it really is. As you turn it, each pleat was pretty disgusting. I don't know why I didn't check it earlier! I just finally got around to the 31k mark and knew it needed replaced at 30.
