and to answer ur first question yes it is connected, the hose is running from the PCV cylinder, but just does not connect anywhere else I have looked all around my intake manifold for like a nipple or something that it should connect into but nothing at all so basically the hose is coming off the PCV but no where to connect, I dont know if after the swap that hose is just not functional or what but with the idel problem I am convinced it has something to do with that hose seeing that I am sure that hose has something to do with the the PCV running to the intake manifold or along those lines somewhere but who knows where, sorry I am a rookie when it comes down to engine work thats why I was hoping someone on here would kinda knoiw what I was talking about and could help out lol
