Problem - Missing Hose and Loose Hose

The title is kind of a failure of a synopsis, but I'll explain better...

I have a '91 4R 3VZ-E 3.0 litre. It has 200,000 some-odd miles on the engine, and we just finished an overhaul.

The problem was that it turned over and started, ran for about 5 or 10 seconds, then dies. The problem now is that it idles pretty evenly at about 800/500 RPM, but dies if I let off the gas a little too long. It also sounds like crap. Rough. Could just be the exhaust leak underneath.

I've gone through the basic troubleshooting, compression is just a bit less than the minimum according to the Toyota service manual.

Now moving on, I have a loose hose coming from the underside of the air intake chamber near all the other hoses and such. The arrow points to where the hose comes from.

I also have an outlet where a hose is supposed to plug, but I can't seem to find the hose nor what either of these things are for. The Toyota service manuals seem a bit... incomplete.

On my 88 the 4 large hoses coming off of/from below the manifold that are under the brake booster vacuum line are for the AC and power steering idle bumps.
 
Look under your hood for the vacuum diagram. You can also search on here for a pic of it. It will help. Worst case scenario, just plug it and see if it fixes your issue.
