O2 sensor?? Which is primary, secondary?
Ok, I'm trying to determine if my O2 sensors are backwards but I don't even know which one is which. How do you know which one is the primary and which one is the secondary??
Thanks, for the help.

Yup the O2 sensors were backwards. Now it works great and m A/F gauge looks like it works like it's supposed.
Thanks!!
