What readings do you have?

Should I be reading resistance or voltage??

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.

[JonDoh]

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.
