Thank you for the useful info, sir. It seems like a hard job to do.
It's actually a pretty simple job, just a tough location. I watched a few youtube videos to get an idea how others tackled it. I separated the fuel line using one of these
3/8 fuel line tools to give my hand a little extra room, and then literally laid a drop cloth over the
engine and climbed up and in, chest down and arms between the engine and firewall. You are basically working blind, so I used my cellphone to take a few pictures so I could see what orientation the wiring clip was on the sensor which made it easier to feel how to pop it off. I did use one of the thin walled deep 1-1/16 socket with a few universal socket joints and various extension lengths. If I remember correctly, I think I ended up wrapping my universal joints in few wraps of electrical tape, so they were flexible but not floppy.
Other than that, take your time, it will take a few attempts, but it is doable and I think the whole project took about 20 minutes.
