Where to begin.
I had an obnoxious high-pitched scraping sound coming from the brakes when they were released, but only in stop and go traffic. I cleaned the brakes and greased the calipers last week but that didn't help. I had a new hunch and I was correct:
There was a small buildup of crust on the outside of the passenger's side rear rotor, and when it would heat up and expand outward with heavy braking, the crust would scrape the abutment clips. I ground that sucker down and now it's as quiet as a rotor that needs to be replaced soon can be.
Next I cleaning the throttle body. It's only been 25k miles since the last cleaning, but it was already gunked up enough to make a noticeable difference.
It was nowhere near as bad as it was when I bought the TrailBlazer with 54k miles, having never had it cleaned.
I'm still hungry for some more performance, so I might see about getting in touch with PCM of NC.
Then I cleaned up the fire hazard I had in my dash that used a random relay out of an S10 Blazer and some peeled-apart 14-gauge speaker wire to operate my footwell lights.
I figured they're low-power enough to not require a relay (heck, I was using a 1A fuse for them before).
I bought some OE foglights from the local junk yard months ago, so I finally put in the OE foglight switch and started trying to figure how I'd get the OE fog lights mounted in my LS bumper.
I still have to figure out which wire is which so I can get a latching relay and start getting the new wiring roughed-in.
Lastly, I figured out putting a resistor on any LED brake light restores cruise control's functionality. I commute roughly 100 miles a day, so that will be a welcome repair.
It was a busy day.
