"...I have my doubts about the vacuum sensor thingy..."

Unfortunately, that's a part known for failure at old age, and one of the pieces you would want to have along with you on the "rescue mission". BTW, it's called a Manifold Air Pressure (MAP) sensor.

If you suck on the hose which is connected to it, you should be able to pull the diaphragm down without any continual leaking. If it passes this high-tech test, there's a very good chance it's still OK.

John's trouble shooting suggestions are excellent. I think he feels like I do that you should do everything you can to retain the D-jet. If you have to throw a carb system on to get the car home, don't do anything to render the F.I. system unrestorable. I'd have to think in the long run you'd be sorry. Good Luck!!
