Did some more work on Rocinante this weekend.

Replaced temp sensor, but temp gauge just will not rise more than maybe 1/8" above the cold mark. :shrug

Since my new alternator belt was squealing at startup, I decided to pull the AC compressor so I could get a bar on it for better tension. Decided to advance timing a little bit, too. Bumped from 7?BTDC to 5?BTDC since the FSM specifies a 2? allowance either way. Had no effect on temps, doesn't seem to have had any impact on the run-on/dieseling thing (which has improved slightly, though).

Pulled the air filter to check the choke and carb for condensation and such.

Cold startup, dirty. Oil coming from EGR?


Cleaned, cold.


Choke fully opens.


Secondary, cleaned.


Seems to be running better, though. Wants to break the tires loose out of every corner, can almost keep up with traffic. And I got over 120 miles out of the first half a tank, which is easily a 40% improvement in fuel economy thus far.

Thoughts?

Also, where is the reverse light switch? I crawled under to replace it, but couldn't find it with any confidence. There are 2 little sensor-like deals on the rear of the tcase (passenger side), one of which has a broken off wire on it, but the one which looks most like a switch is more on the rear of the trans(also broken wires) and none of the loose wires - yellow tape, bullet connectors? - seem to reach. :shrug
