Two spark plug anifoulers installed on the second O2 sensor. NOT ON THE HEADER
One drilled out with a 1/2" bit to fit the O2 sensor and the other left alone.

I tried it with just one antifouler and it still gave a CEL. I added the second and my CEL went away after a few days. It hasn't come back for over 1500 miles!

 

^^ where can you get those from and how much?

 

now if only we could get someone to make them that way

 

Your local auto store will have them. I got mine at Pep Boys.

It's so easy! You don't need anyone to make it for you.

 

Is this a fix for the DC Sports header?

 

some call dc and tell them to ship this thing like this

 

Nice work. I remember people with gutted cats on another forum doing the same thing. Sweet idea. If I remember right they bought 2 18mm antifoulers and drilled a 1/2" inch hole into one. Then attached them both like you did, which creates a space that fools the sensor into thinking there is a cat there because its reading less 02 at cooler temperatures.

If you used 18mm antifoulers also let us know thanks.....

 

That is exactly what I did with 18mm antifoulers.

I forgot to say that this is the SECOND o2 sensor we are talking about.

 

Wow!! I am impressed, that means that the O2 sensor is gettin hot enough to respond back to the computer!! That great, maybe I need to start making those here at the scion central. :D

 

Wow the fix looks great and cheap i wonder if any long terms problems will be an issue.

 

I highly doubt any long term affects could arise from just installing antifoulers. I'm gonna buy them and drill the holes and put them on my dresser to remind me to buy that damn header lol

 

Now i've got a quick question for you guys that are having this CEL. Is it throwing a Bank #2 Rich type code?

Cuz right now my xB is catless due to my greddy turbo kit and i'm throwing that code. And it would make sense to do this same mod on mines.

any help is appreciated.

duey

 

yeah it should work on your xb also basicly both sensors are showing the same reading the point is to make the 2nd sensor have a lower reading so it thinks a cat is there i would go a head and do it should work fine

whats your xb running with the turbo? can it take a civic si yet or is it still a little lacking on power?

 

still tuning the emanage, but i'd like to fix the CEL before i do anything major at this point. Only dyno'd at 115fwhp at 4psi of boost and it pinging a lil bit so i can't really push it hard yet. But according to GReddy i can/should lay down 120-140whp with proper tuning which i hope to accomplish eventually.

 

sorry to be a total newb. but what am i looking at? where is the 2 drilled holes and what is being drilled into? how come i did a search for anifoulers and couldnt get any info, what do they do? can i do this at home?

 

Will this mod work when you remove both cats or just one?

 

the second cat doesnt have any sensors so pull it off if you dont want it just remember there are emissions test in indiana

 

HAHAHA!!! What are you smoking. We don't have emissions tests here. I have never heard of anybody in Indiana ever getting tested. But thanks for the tip I may remove the second cat when my exhaust shows up.

 

Here is a how-to with pictures.
