Okay, the search couldn't get me this which has been repeated a bunch of times - can you go ahead and wire both O2 sensor wires together on the output of a single o2 sensor?

I have always used two but have a jdm header i don't want to mess up with drilling and flanges, etc...

thanks, all

JDM CRX

Im asuming you have a oBD0 b16 swap in a 88-91 CRX/civic. My car was running rather wierd with just one of the Two wires connected to the O2. So i ran both the wires into the single wire O2 sensor. The problem almost went away, it was still kinda wierd in certain RPM's. UNder WOT it was fine, no problems, but when you are partial throttle on the highway just cruising, it does some wierd stuff. The power seems to fall out if you are at partial throttle. IT only did it under 4k RPMs so i kept it a little above 4k. This was a b16 CRX with the hasport wiring harness and stock JDM pr3 ECU.
----just what i experienced.
