i swapped a b16a first gen into my 89 civic si hb and im only running one o2 sensor and it doesnt trow a 2nd o2 sensor code i installed the 2nd one and wired it to da computer but it runs rough and nasty but unplugging it runs how it should. Could it b that the computer is chipped to not run a second o2 or wat? anybody come up with this problem or anyone has any sujestions on how to fix it?

 

I may be wrong but if you are using an obd0 ecu, the computer only sees one o2 sensor

 

so hook up the other or just leave it like dat?

 

which ECU are you running? the LS one or the B16 one?

 

im running the b16a one the PR3 crazy **** too was that wen my throttle position sensor(tps)was fuked up and would sumtimes have the check engine light it would act all cool with both o2 sensors but once in a wile wen the tps i guess would fix it self and the check engine light turned off thats wen it would act all stupid. I already fixed the tps and lights off but car acts stupid so i just unplugged the 2nd o2

watcha think might be fucked up or wats wrong?

 

anyone else?? help!
