It wouldn't hurt to replace the o2 sensor, since it is properly 20+ years old.

/\/\ true. Does your multimeter not read that low? Should be a one's unit. A 2 by itself on the multimeter. For as much as the values changed it seems to be working. Usually when they go bad it will read the same voltage or around the same constantly.
How is your temp gauge reading? Coolant sensor in the head will screw your mileage up too. Check the ohm values in that alsoDENY IGNORANCE!

Hmmm yes. Just trying to avoid buying something if it is working.
The temperature never rises past the half way mark and usually just sits on or just before the first quarter mark. Takes awhile to warm up.
the thermostat was changed less than a year ago along with the coolant being flushed out.
I'll check the coolant sensor too. ThanksComment
