how long does that last w/o the CEL comming back on? b/c i tried that and it came back on in like 3 hours of driving.

 

i did this and for the 6 months i've been driving after doing this...the cel only went on once, prolly after around 5 months. i reset doing the battery trick and everything's good again.

 

Well, it's not supposed to come back on at all, it should be a permanent thing. Did you drill it too much where the O2 is too far in? Maybe experiment with two new foulers and don't drill it in as much as the one's before.

OR

The CEL is not related to the 02s? Do you have a scanner to log and see what the CEL is?

It's frustrating I know...

 

My issue is that the plug on my test pipe for my 02 is in a position where I can't fit two foulers so my CEL keeps coming back.

Another guy with an IX has only one fouler in place and he doesn't get a CEL but he's running a different tune... UGH!

 

Alright! How the F do you get that damn o2 off there? I've tried about 5 gallons of wd-40 and a hammer, and still nothing...

 

does any one know if the TTP test pipe has the O2 bung welded on it? i am getting it to replace my cat and i dont want to have to extend the o2 sensor to reach the back of my cat back....

this Anti-fouler worked for 2 years on my nissan with not one code ever thrown...

 

it does.

 

I did this mod today, using the same part # foulers... drilled with a 1/2 bit and all the autozone o2 sensors wouldnt fit. They were too big. The o2 sensor was actually 1/2"... are the secondary OEM o2 sensors in our cars 1/4" ?

 

I remember I was skeptical too. But if you follow the directions exactly it will work. I did it on mine and wall la.

Just out of curiosity I looked up an o2 sensor for the evo and they didnt have any. So I looked up one for a 98 eclipse gsx and tried to fit it into the non fouler after I drilled it and it did not fit. So the rear o2 sensor on the evos much be smaller.

 

Ok, perfect. They were using 'universals' that were to big for my 1/2" drilled fouler. I figured that was what it was.

 

10 months (today).....no CEL

 

I have just one non-fouler on my IX and haven't thrown a code since day one.
And that was 10 months ago.

When i did mine they stripped the threads on my 02 sensor getting it out.
I thought I would have to get a new sensor, so i ran a tap/die over the threads and it screwed in perfectly to the
non-fouler and then non-fouler into HF cat perfectly.

I saved myself alot of $. phew..
Dealer wanted like 350$ for a new rear 02 sensor..

 

I performed this mod a while back. I cant remember what size bit I used to drill the anti-fouler out. My o2 sensor (the protruding part) fit a bit tighter than in the pics above. I have had ZERO CEL's including 4 laps of the Nürburgring and the drive from England to Germany. It works!

If you want a cleaner install get the electric CEL fix from Helix. They usually don't come with instructions though. Still easy to fit though. Two wires are the same color and you just slice them in-line (ground I believe) and then use a DMM to check which way to wire the resistor wires. You want to "cap" the voltage on the return side (to ECU). So the o2 side wire will have a higher voltage than the ECU side once the resistor is installed. Make sense?

 

newb here my cel or ses came on and i went to autozone to find out the code it tells me that i have a bank 2 or cat sensor so i found this forum and tryed it out my evo keeps on dieing on me or it boggs like crap could anyone help me with this and plus should i dyno my evo even though its still stock all i gots under the hood is bov and aftermarket exhaust. thanks

 

Swap the stock BPV back on.
