No, you just get one trouble code constantly. I have the 97 ECU in a 99. The rear O2 sensor is a different type and I never switched it so the ECU thinks something is wrong. The problem is that you can't tell if a new trouble code appears.<font face="Verdana, Arial" size="2">didn't you get a bunch of trouble codes driving around without it? </font>
what you can do is find a nut that screws onto the o2 sensor, drill a hole in the test pipe, and weld the nut in its place.<font face="Verdana, Arial" size="2">Originally posted by nitrous_50:
o.k., quick question to b14 owners.....
we have obdII emissions, therefore, we have an o2 sensor in the manifold, and an o2 sensor in the catalytic converter. if you run a test pipe in place of the cat, what did you do with the o2 sensor
