I was looking at some live data today as I have a code indicating a kat below effiency.

I wanted to check the o2 sensors and I would really appreciate some help.

the front pre kat o2 sensors are both showing 0.9 v constantly, does this mean it is running very rich?

I am using Carly and I am wondering if it simply doesn’t show the cycling as it happens so fast?

fuel economy seems a little down.

I have no codes relating to mixture at all

any advice / help would be appreciated
