But you should DEFINITELY do this so you will know which sensor - or both - is causing your CEL.

 

Well i installed a second hand a/f sensor...after a while of driving the cel came back on.....so its the headers i hope.
Can anyone answet me hom much foulers i should use on the second sensor??
Im using 2 now...but i read people using megan headers like should use 3 is this right???


Ill put up the part number as soon as i can

 

like i said, sometimes it doesn't work. a antifouler isn't even the right way to do it. all your doing is tricking your ecu into thinking everything is ok. i haven't dome much researh on headers since i'm not planning on getting one but you might be able to fix it using a piggyback and a good tune. not sure tho.

 

Take your car to autozone or advance auto and have the code read for free, this will tell you what sensor it is.

 

Well im on an island in the caribean, no autozone here

 

Well, ZPI supposedly sales OEM 02 sensors, and the front one is 195 I believe. I just bought one from them. However I also have the Invidia s-pipe and got this from the guy that at the time told me he had 2500+ miles running on it and no CEL yet, so hope mine works from him. It might work with the stock s-pipe, don't see why it won't as the threading will be the same, but maybe the angle could throw it off some, dunno hope it helps though. https://www.scionlife.com/forums/vie...210&highlight=
