I just need to know where the bottom line from the airbox connects to. My van was running very poorly lately, and one of my friends said something about vacuum lines and I knew right where to go. I found one line not connected to the air box, the top one, which goes to the rear valve cover, and I thought there was supposed to be one on the bottom too but there wasnt a line in sight. I then went to the other 3.0 engine that is in my garage and found a line on the bottom of the air box, but I couldent find anywhere it would connect to. Basically I just need to know where both hoses from the air box connect to and from. Thanks.
