When I went to clean my MAF sensor I found a loose hose. I'm not sure where it goes but I think I found where it connects to. Even though I connected it, it seems that there was probably an extension piece because it wasn't long enough unless I detached it from the air box. There was some kind of snap connector with a wire tie that secured it to the top part of the air box. It must not be all that important since I didn't have a check engine light and the SUV seemed to drive OK. After connecting it to where I think it should be connected the idles seems to be lower.
