Cleaned the MAF today and reset the codes so haven't had a chance to see if that's the fix.

We were having some trouble figuring out where the pcv is in the care (not as obvious as my v8 Mountaineer) and found an elbow driver's side in the back. Elbow is either the one outlined in the picture or one right behind it, I think. Followed it down a few inches and got to a piece of plastic. Was able to move that in and out about 1/4" or so. Not sure if it's supposed to do that or not. Should there be that much movement at the end? Is that the pcv?
