Should I be reading resistance or voltage??

Are you installing an o2 efie along with a booster?
And if you are you will be ckecking voltage at the o2 sensor.

no booster or nothing yet..... just wanted to see what kinda reading suppose to get off an O2 sensor before I use an EFIE...... but it might not be neccessay because without any enhancement on the 93 Lexus LS400 there was a 10mpg gain with 2 O2 sensors before the catylic so I don't know if I need an EFIE or maybe I should use one to try to squeez more miles.

Perhaps this will help you.
