Gorgeous leather -- it's easy to forget how nice these cars looked when new.

Thanks for the feedback above. I got so much education and money savings out of this website I wanted to contribute something back.

I bought a Tekton socket last year in January (2021), and that worked great -- did not open up or spread noticeably while removing the old O2 sensor. It was a TEKTON 3/8 Inch Drive x 7/8 Inch Offset 6-Point Oxygen Sensor Socket, part number 47749. Only cost $8 at that time, now $11 in Oct 2022.

I heated up the fuel filter with a hair dryer -- enough hea...

From the description of the fan running at full speed, I agree it sounds like the power stage / fan speed controller may have failed. One of the failure modes of the power transistor is to fail "closed" which causes the fan to run at high speed. On the blower motor, my experience was that ...

I have had good luck recently sourcing parts from Voluparts.com in Atlanta. Another good source would be from Robert Spinner, who has a great YouTube channel RobertDIY.
If there is a local junkyard available, you might be able to find the part there.
