I have an 86 Porsche 944 NA. I recently took my top end apart to rebuild the head (broken timing belt) and this thing, that I've concluded to be the TPS, was attached directly to the bottom of my intake manifold. Upon putting it back together, I've realized that it doesn't fit right under there now. And I suspect that there should be an actual hose where the cut one is? Can't seem to find the hose online.

My second problem is: apparently, the PO used sealant to hold this pipe on the bottom of my intake manifold in place and now it just keeps falling out. I'm new to the Porsche world and help would be greatly appreciated so I can get back on the road.

That thing is the idle stabilizer valve.
It mounts on the bracket shown to the right of the "thing" in your first picture.
See those black dots on the bracket? There should be 2 rubber stand-offs there, and the valve gets a sort of clamp bracket installed on it to attach to the bracket on the engine.

That barb from the intake manifold can be re-secured using epoxy (JB weld or the like)

Thanks for the help. So is there a certain hose that I need where the hose on the left is cut off?

If you pull up a diagram (on AutoAtlanta) for the engine it will show you the hose in question and the part number. There is a bracket with two small rubber isolators and a rubber gasket that wraps around the belly of the valve and then bolt to the top of the engine, under the intake manifold. You can get a better visual by typing in "Porsche 944 idle stabilization valve pictures". There will be numerous pics showing different views of the installation.
