Well, this is funny because I have the same exact car and it does the same exact thing. It's been doing it forever now. Sometimes it'll even die at stop lights.
Check for an open between the AFM ground and IAT sensor (it's bundled with the AFM). Mine's open and needs a new AFM. While I don't belive this would cause the problem, if you have the same issue, then maybe it is. Normally it would just make the engine run richer all the time, and I have seen this on my O2 sensor.
I've checked my idle control valve, fuel pressure, changed plugs/wires/coils, removed intake manifold and changed gaskets along with all the vacuum hoses etc., checked the TPS sensor, checked my purge valve to make sure it only purges at cruise... Everything checked out fine, 'cept for the AFM's IAT sensor. The only thing I haven't checked is the coolant temperature sensor, mainly because I remember it being in a hard to reach spot. I'm thinking of just buying one and seeing if it helps. However, I know the IAT sensor is shot. Anywho, keep this thread alive please!
