alright well i fixd all my CELs and everythin was workin good, but couple days later my CEL came on again for my o2 sensor. i replaced it again then couple days later it comes on again. but when it goes on, it only goes on like 30 mins after drivin or if i brake a lot then when i turn off the car, and back on its off then etc. im just wondering what could be causing this? btw i have a jdm d15b in a 97 civic

 

im not sure but check the wiring, could be a loose wire somewhere.

 

on the o2 sensor? but i kept on replacin it , im on my 4th o2 sensor within few months

 

someone?

 

I would'nt worry about it unless it's time for a smog check. Which O2 sensor is it, Bank1 or Bank2? Wait, let me answer. Is it Bank2? If so, it could be because of your catalytic converter is about to take a dump. But like I said don't worry about it until your almost due for a smog test.

 

nah its sensor 1 but yea, im just scared if i leave it fuccd up its goin to spread and make other things wrong
