I've been trying to work these loose for like 45 minutes but I can't figure out how to easily get at the driver side ([ http://m.imgur.com/aaepdyS ]) PCV hose, mostly since its blocked by the black plastic wire holder in the picture. I can't figure out how to take that off either. On the passenger side, ([ http://m.imgur.com/iYnwtH3 ]), I don't know what is screwed into the side of the plenum, as the article on z32.wikispaces doesn't show it as far as I can see. please help?
