On our 2004 2.4L Dodge Stratus I can hear a hissing. I found out our engine was missing a line. I have looked in our Chilton's guide and have found nothing. I was wondering if anyone has any idea where this line is/goes. It's right behind another vacuum line. I have added a link to an image. Any insight would be greatly appreciated. Thank you!!!
