Does anyone know where the vacuum hose off of the TGV Sensor on cylinder four go? I have a misfire at cylinder 4 and I’m going crazy trying to figure it out. I found this vacuum hose under the intake manifold and I can’t find where it connects.

That's correct. I went to hell and back trying to figure out wtf that was for when I did injectors. Turns out, it just sits there.

yeah, ramon120 discussed this with me yesterday. He posted on another forum and found that the hose is just a drain for condensation. Makes sense I guess, must have a one way valve or something to maintain pressure.
Well still doesnt really make sense. If it has a one way valve to keep pressure in then water cant get out. Unless it is only closed when under pressure.:confused:
