How Many O2 Sensors
I have a 94 Runner, 6 cyl, 5 speed. How many O2 sensors should there be? I found one pre-cat but can't seem to find any other. Thanks for the help.

I have a 92 that I bought from the original owner in California, and it was purchased originally from a Toyota dealer in California and it has only one O2 sensor and it is in front of the cat.

Thanks for the help. I know I'm not going crazy finding only one.

O2 Sensor
???Hmm, I'm fairly certain 4Runner's have two O2 sensors. One in front of the converter and one behind it.
I could be wrong, but I don't think so.
