so this is going sound stupid i really dont care but im changing out my s pipe and all that this weekend to get my cutout put in now if i bought the anti foulers and place them in the s pipe for the 02 this wouldnt get rid of my cel would it jc because i dont want to waste my time if its not going to

 

most of the time it works...take two of the small antifoulers, drill one of em out big enough (1/2 should do), put the sensor on the one that drilled out and stack the other one on it.

 

ok u think it will work being boosted an all

 

It should.

Depending on how stringent your state inspections are it may have trouble setting the monitors but it won't trip a CEL.

 

ok sweet im have to try this this weekend then i guess its worth a shot lol plus im sick of looking at a cel all the time lol

 

first what code are you getting?

 

What kind of spipe do you have? I have the invidia and that doesnt give me much room for the anti fouler trick. I had to get the weapon r cel eliminator.

 

I thought you didnt have to put an anti fouler on the s-Pipe?

 

who told you that?

 

im not sure what code im getting an ymore i just kn ow its a 02 i forgot what the code was lol and i have a s pipe made from a exhaust shop what is the same as stock s pipe just 2.5 piping sioze

 

if it was p0420 then your heading in the right direction...anything other than that you need to look into o2 sensor condition, wires, and so on.

 

I'm getting the same p0420 CEL, but the s-pipe I have doesn't give me room to use the small anti-fouler trick.

Besides the ant-foulers, is there another way to eliminate that CEL?

 

Unsolder the LED on the board like I did when doing my LED Swap Or, take off the cluster and stuff a bunch of electrical tape in the opening for the engine light! I got rid of my TPMS light and CEL light. I use a scangauge and regularly check for codes.

BTW, I'm boosted and I don't use an anti-fouler and don't have a CEL for P0420. Weird.

 

i had to use 3 anti foulers when i had my megan header...there still in there now but i have a stock s-pipe and could see what you mean about room. they sell a L shaped attachment on ebay for 20$ that might work for you.

 

Yea, I might have to try the L-shaped one. It looks similar to the weapons r cel eliminator.

Anyone use the weapson r trick and know if it works?

 

when i was n/a i had to use 3 anti foulers..... when i went turbo i kept getting a different rear o2 code it was bank 1 sensor 1 high voltage or something like that...so i removed the foulers... i got a check engine...but then it went away on it own and never came back =] a good tuner will be able to tune for the no cat or fouler

 

Lucky you!

Haha, I had no idea you could get a tune that would resolve the p0420 cel.

I'll have to call my tuners and ask them wtf! lol

 

its something i know is possible with the aem fic seeing as u can alter the front o2 readings.... u can get them in that range of where the fornt 02 and second o2 need to have a variance

 

Hmm, I have the aem fic. I'll def. be calling my tuner about that then. Thanks for the info!

 

3 anti foulers also worked for me
