Hi i have been trying to diagnose my p0300 code and first thing i noticed was im missing acouple vaccum hoses. I looked at the diagram on alldata and the one under the hood with no luck at all of identifying where they go. Anyone have a better one or could direct me into the right path? thanks! Please view the attached pics to know what im talking about. Also i forgot a pic but the small nipple in the direct front of the intake manifold on the passenger side was connected to a vaccum guage that i disconected so i need to know where that line went too. Thanks!

 

Those two look like the hot water passage to warm the throttle body.
