B16a faild emmisions 02 problem
I just faild emmisions in Colorado today. I through a O2 code intemittenly so Im going go change the O2 sensor and try again. What sensor is sensor A on the exhaust manifold because I think it might be possible that I got the two O2's fliped during installation.

Re:B16a faild emmisions
sorry, Im running a pr3 ecu so its OBD0. I have a new cat but its kinda small. Im guessing O2 #1 is for cyl. 1-2 and O2 #2 is for cyl. three and four. So, do does the 2 single wire o2 set up typicaly run rich? and what can i do to fix it.

Re:B16a faild emmisions
if your only running one o2 then you are going to run rich, if your running 2 o2's then your hurting. i did notice that i could NOT use an USDM o2 sensor on my pr3 i had. it could have been bad but the new o2's from napa look the same as teh JDM ones. who swapped your motor out for you?
