Our 2008 MDX will sometimes have the idle stumble (drop 200-300) rpm when the air/heat is on. I don't think it matters which it is. If just sitting in the drive way at idle and not going anywhere it will stumble. It's slight, the car is not going to die or anything, but something is going on. If i turn off the air/ heat the issue does not present itself.

I thought I found this in the forum, but could not find it this evening. I'm certain this has been discussed. Thoughts.. more of an annoyance then anything at the moment. Just 82K on the car. Go team MDX...
