I just installed a JDM header and new exhaust on my GSR. I had the muffler shop put a new O2 bong right after the header. it ran great for a few weeks now the check engine light came on. i pulled the code and of course its that O2 sensor. Any ideas what to do?

 

check the wire/wires coming from the o2 sensor, you can try to pull it and clean it off, rest you ecu and see what happens.

reset your ecu and see what happens

 

it might sound dumb but what do i got to do to reset it.

 

pull off the negative battery terminal for a few minutes

 

didnt do a damn thing. could it be the positioning of the O2 bong. could it be that the sensor is to far in or not far enough.

 

my friend did this to me as a joke if you unplug a sensor or vacum then you computer will say there is a problem, thus the check engine light, and it will stay on until it is rest so he would have only had to unplug it then plug it back in and you will still have the light, so just pull it off and wait a little bit the put it back on and see.

 

might help but i put it on the wrong one, had like three open at once.

 

alright. ill give it hell. thanks
