I'm not saying it will solve your problems completely, but I suspect the coil should be replaced. You can pick up a decent PS91 for under $50, and install it in two minutes. That's the best I can recommend without actually seeing it. You've tested the fuel system, you checked for vacuum leaks, you've confirmed that there isn't excessive backpressure in the exhaust, and you've tested the rest of your ignition system. I learned a long time ago that the easiest way to start a diagnosis is to remember that it only takes 4 things for an engine to run:
Air, Fuel, Ignition and Compression. Have you checked your compression? If your vacuum is steady at 17", your compression is fine, but you might want to check anyway. I'd try the coil.

Take care
