I am only running 1 O2 sensor right now on my 96 b16, since I am running without the cat I only have 1 bung for O2 sensor. As I've learned in another thread from Pills, missing a O2 sensor signal gives me fuel delivery problems around 3000 rpm under partial throttle, my question is this: Can I splice the O2 sensor wires so the ecu gets the same reading for the 1st O2 sensor at the end of the exhaust manifold and the 2nd on the cat? People running dummy cats have 2 o2 sensors but I'd imagine they get pretty much the same o2 levels. Has anyone done this or is there a problem with the ecu seeing a certain amount of ohms/amps/volts (i am an electrical idiot)? thanks.
