First thing we did today was physically check the timing at the balancer, and lo and behold, it was reading around 30 degrees, not 38! It's more than a little disconcerting to me that it could've moved that much in the first place, but it sure does explain the car running like a pig lately. It's a FAST Dual-Sync distributor. We went through the setup procedure again, checked it against the timing light, and tweaked to match. We marked it before going through setup again, and you can see the distributor is definitely in a different position than it was.

Just goes to show you can't overlook the basics, even if it "shouldn't" have happened. Hindsight, Sherlock Holmes, Occum's Razor, etc, etc.... I'm sure I'll have to punch the fuel map around a bit again now, but feels good to have actually found and corrected something that is a definite problem.
