Vacuum help/Engine Help needed!
so my car, 1993 sc300 auto, is running like crap out of nowhere. Idle bounces from 300 RPM to 2k RPM and blows black smoke out of the back(when revving not while idle). It just randomly started happening. It will stall out sometimes. It drives like it has no power and feels like the clutch is slipping when taking off (it's an auto, but it has that feel like when a manual slips). Has new spark plugs (2 weeks old).
There are no leaks that I can see and the engine does not overheat.
Attached are 2 pics, first for reference to see where I am looking. Just below the back of the intake runner (near the last fuel injector), I found three metal hoses that look like airlines with nothing connected(circled in red). Maybe this could be part of the problem? Could someone please take pics of where these should be hooked up? Also if you have any ideas about the poor running engine I am all ears.


EDIT: I'll leave my questions in case someone else reads this. ECU numbers must match or there could be issues. I didn't think the obd2 ecu would work but I was hoping!
