So after we had removed the tmic and was getting prepared to put everything back to where it went, I found a hose that no one had noticed. We cannot, for the life of us, figure out where this hose goes.
I have pictures for your reference, the first of the hose - the second of where the hose goes into (some solenoid?) - and a third kind of backed away so you can see the whole thing.
I really need this help as soon as possible so I can drive my car! Thanks a lot.
