do you not even have the stock one ?, but yes if you dont have it buy a secondary 02 sensor and put it where i said and the cel will go away
Hey ahhvtec:
Just for my own information, does the location of the secondary O2 sensor matter? I'm talking before vs. after the catalytic converter. On my car the primary goes in the down-pipe and the secondary is after the cat.
Does that matter or does it just matter that there's two of them somewhere in the exhaust stream?
