Been stalking on here for a while but i neeed some help. Recently swapped a 2jz ge into my 01 is300 because the old engine had mechanical issues. At the end of the swap now car runs and drives but is throwing codes for a vacuum leak. I found the leak, its a hose that came off at some point during the swap (i can feel the suck when i put my finger to it). I have looked and looked though and cannot find where this hose connects on the car. Please help!
It is the part im touching with my finger, on the right side of the intake manifold assembly
