Alright, so I must not have been getting a good enough connection to the wires. I fixed that...so now I KNOW I had it connected right and I'm pulling about .450 volts. So.... 1/2 a volt.... Is that within spec? (while the engine is running btw)

The reason why I think my o2 was/is bad is because I'm getting terrible gas mileage, and it looks pretty old, so I just thought it might be bad. I tried pulling the codes, but there were none to pull. So I wanted to make sure it was either good or bad before I spend $100 on a new one.

My 'rig'

1992 4Runner 3.0 automatic
31x10.5 BF Goodrich AT Tires
Cleaned throttle body
Sea foamed the gas tank, twice.
Tires properly inflated

New K&N Air filter
New NGK plugs and wires
Tires balanced, front wheel bearings repacked, and front end realigned.
greased about 6 Zerk fittings on the drive train, still need to get at a few more.
