hey sensei , still no CEL ?

hashmanson76

thanks for the write up im gonna try this in two weeks when i get my megan header thanks wish me luck

bigBOAT

does it go off with the injen cai and a dc header, just ordered my header today. do i need to do this

So does it still hold true that I won't need to use an antifouler for the Megan S-pipe that I'm getting here in a couple of days? I ordered that along with a Megan header. Should I be good without an antifouler?

i have the megan header stock s pipe and ingen CAI and it went off ill be doing this mod today to fix the cel

hashmanson76

i did the fix yesterday the 13th reset my ECU with a friends little CPU that connects to the port by the lever to open your hood, got on the freeway this morning cruising at about 85 for 5 min. no check engine came on thanks

what is this $50 fix that everyone keeps talking about? i just installed megan headers and a zpi 2.5 inch mid-pipe and i got 2 things wrong.
1) CEL keeps coming on
2) it is so flippen loud i got one ticket already and have been pulled over like 3 tims after that. sucks. what should i do about the noise?

hashmanson76

i bought a silencer for my ehxaust that should help and dont gas it to much
I have a megan header and a tsudo mid pipe and cat the only thing i dont have it the S pipe, i did the anti fouler fix and so far no problems

hey well i got the trd axle back. do they make one for it and if tey do where can i get one?

hashmanson76

measure the diameter of the tip is should be 3 1/2 or 4 1/2 and you can find one at any performance shop they might have to oreder it thow good luck

How can I know if my O2 sensor is bad or good? I took a reading of the CEL and it gave me excessive emission, which makes me assume that the second O2 sensor is working... right?

-doomed-

yup the o2 is working if it wasnt there would be an o2 code

when i get a header i plan on welding in a cat right after the s-pipe and moving the 02 sensor just so i dont have to ____ with it anymore

I reset the CEL to see if it will turn on again. It's been about 130 miles so far an no CEL. Last time it last 'till 185, so let's see...

As for moving the O2 sensor to a location after the s-pipe, talk to someone who understand better than I do, but I heard that moving the sensor to a further away location can give you a CEL for some other reason. I also heard that if you move them closer to each other (to the one on the header), it may eliminate the CEL. Again, these are things that I heard from a mechanich friend of mine. I'm clueless about it (if I knew I didn't have the CEL, lol).

Good luck

ive tried all of these things everyone has mentioned and no success so far. what would you do if you have tried all the antifouler tricks with no luck.....would you reinstall the factory header or stick with side affects of the cell? is the header worth that much when it comes to the cell? i would relocate the sensor after the secondary cat but not forsure how to do so. and has anyone tried the piece of catalyst between the antifoulers?

MrChoyBoi

I read somwhere about puting a small piece of catalyst from your stock cat inside the antifouler. Not quite sure if it works or not, but im open to ideas because im also having this problem. Just tired of reseting my ecu every 1000 miles or so.

Kall

I had to reset mine again at 170. This weekend I will try to remove the antifouler and reinstal. If still doesn't work, I'll try to drill a very small hole on the side of the fouler so that the gas can mix with pure O2. Hopefully this will trick the O2 sensor. I'll post any results here.

Kall

Here is what someone else tried... I'll try this too

pimptc

let us know how it turns out
