Rogue Vacuum Line - Where does this go?

[Spaceman828]

Hey Guys, need a little help here please!

Just replaced the Camshaft position sensor and can't seem to figure out where this line is supposed to go. Put air cleaner back on and drove around, pulled codes for cylinder 3 and cylinder 4 misfire with fuel cutoff. Camshaft position sensor code is gone.

Thinking this line has something to do with it, before I replace coils and plugs. Any help greatly appreciated! First picture shows where the line is coming from, below the engine.
