So my 2100 RPM squeak vacated the building. Drove it last night. Completely gone. Same tank of 87 octane.
I had the center grill out to install a bunch of little round running lights. When I reinstalled it, I zip tied every loose wire and anything else. Not sure if it helped.
I did spray the serpentine belt with a couple of good sprays of brake kleen while the engine was running. Didn't seem like it did anything at the time. Drove it about 5 miles up through the gears and no squeak. So I'm leaning towards a serpentine belt or out of alignment engineer pulley that was temporarily appeased by the brake kleen.
I was going to make a video of the squeak. Glad it is gone. Hopefully it stays gone. Thank you to all the replies.
