Yeah, I know Otto. I was just curious about what the O2 sensors actually measured, specifically on my Sequential Fuel Injected 3.4 V-6. Everything I read on it, was the computer controlled the duration and timing of the injectors as well as adjusted the ignition timing to maintain a 14.7:1 fuel ratio, with the O2 sensors providing the major feedback to the computer after the inlet sensors did their input to the computer and after actual firing in the combustion chamber. Modern technology is a wonderful? thing.
