07 CX9 has low idle, sometimes will die
Recently my CX9 has seemed to have a low idle. When I am in park the idle will occasionally drop very low, like 3-400 or so, then the car will catch it and jump back up to normal. Every once in a while it drops and the car doesn't catch it and dies. It does not give a check engine light, and restarts fine.
It only seems to happen on very hot days, the cars temp is right at halfway, not overheating. I do have the AC on and it does seem to drop rpm when the radiator fan kicks on.
That is all i can think of. If you have any advice on what I should look at first, it would be much appreciated.

It sounds like the engine is not getting adequate fuel? Maybe the injectors are dirty? How about you plug in a ScanGauge II and watch some data coming from the ECU?
