Does anybody have a really good understanding of O2 sensors and LTFT's on our cars. For the longest time I thought I had a 1 volt o2 sensor and now I am starting to wonder. The V8s have an O2 sensor that reads .89 - .91 as the stoich ratio.
This is fine if you have a 1.5 volt O2. I thought this whole time I was running rich because thats what my gauge said and so does autotap. After some brief discussion with those guys I got to thinking that maybe mine is also a 1.5 volt.
My LTFT is fine and stays pretty close to o%. Actually its like 3%. If I were running rich wouldnt the pcm try to compensate and shift the trim down some?
If anybody knows or has a helms manual please let me know. I have a chiltons and it says that it should be a 1 volt.
