It looks like cylinder #4 is having compression problems. All of the other cylinders have adequate compression, but a simple compression test has found the base issue. I need to perform a leakdown test to find out what part is failing, but I can't seem to justify paying $150 for a tool that I'll probably use only this one time. If anybody in the Seattle area happens to have one that I could borrow for an afternoon, I'd by you lunch if you would let me use it. Really all I need is a hose that'll attach to an air compressor and to the spark plug hole so that I can put enough pressure in the cylinder to hear where the leak is.
