Hi Ryan,

How's your alternator?
The codes were running rich or lean/ and O2 sensor and I replaced the
O2 sensor a few months ago.
With a bulk of short town driving and getting ratty mileage 14-16Mpg
I found plugs (NGK copper) 2 and 3 with a good looking center and a ring of carbon on the outside. So I was interested in checking the engine temp sensor for the CPU and measure it at the right post connector- but the greenbook
color codes don't jive up. Then cold weather struck Beantown and it can wait.
I was happy to see 26MPG on a rare highway excursion though!
Maybe the CPU and/or O2 sensor cable connector pins need some TLC?
The old connector/s are in there untouched since I spliced in a ford sensor
from underneath.

Happy New Year, Bill
