I have an 89 crx with a b16a, obd0, with two o2 sensors. My Megan header only has a spot for one. Is there a way to piggy back the o2 sensors into one, or will I have to find a new header? I don't want a CEL, therefore, I'm trying to find out what I might have to do. If you can help me, that would be greatly appreciated. If you could direct me to someone that might be able to, I'd appreciate that too as I'm lost about this one...

 

if you have a pr3 ecu you'll have to run two o2 sensors. if you have a pw0 you only have to use the one. when i had this problem i drilled a hole in another exhaust runner, welded an o2 bung on and ran the second o2 straight to the ecu

 

ya, I wasn't sure what I needed to do.. I was hopin I could run a two wire o2 sensor and call it good... damn it
