I replaced the plugs today and put a bottle of some Lucas junk in a fresh tank. On my way home from work I didn't notice the hesitation but it's intermittent so I'm not certain it's fixed yet. I have a new factory O2 sensor on its way.
Was a bit sad when I opened the hood and noticed some oil on the bottom of my A/C high pressure line and also around my power steering pump - those definitely weren't there a few weeks ago. Although the power steering pump will probably be an easy fix, air conditioning never is.

My timing is already advanced, or at least I think it is. I bought a timing light last year and I was actually unable to see the timing marks at all (though I've never timed a vehicle before). One of the symptoms of advanced timing on my engine is a high rolling idle and I ended up adjusting it until the idle was where it ought to be when rolling in neutral, and then advanced it just a bit from there. I don't get any predetonation even with it fully advanced though.
^ I doubt my timing is the (direct) cause of my recent troubles though as it has been fine for the better part of a year and only recently developed these problems.
