Hello all .
I have a post similar but my topic is more about post cat narrow band sensor. I would love some help in my situation . My main concern is the roll of the post cat o2 sensors in its roll with the pre cat o2 sensor.
And sorry if any of my information is incorrect I am still learning. I have a n55 and I have heard that they rely more heavily on the precat sensor is this true? Does anyone have any links?
And sorry I don't mean to try to draw attention away from you thread but if the secondary does affect wideband o2 then maybe it will apply to you?
Please read and help me thank you..
Post cat o2 sensor! What does it really do for dme?
