Hi all. Recently I was replacing the vacuum hose coming off the PCV valve going into the intake. In order to get to it I had to disconnect some lines from under the throttle body and I realized a day later I must have forgot to hook one back up as there's an open port and car runs rough unless I plug it with my finger or electrical tape. So, under the throttle body there's a piece that has 5 lines hooked up to it. There's a stiff metal one going into the middle, two on the passenger side and two on the driver side, the ones on the sides have rubber boots on them. I have nothing hooked up to the lower port on the drivers side. Does anyone know what is supposed to go into this port? It is definitely a vacuum line of some kind as there's is suction coming from it. Thanks for any help!
