Okay so my check engine light came on last night. I didn't do any engine modifications lately.....Before i have installed CAI, headers and an axle-back exhaust (HKS) Now probably a month went by, or even more since i installed the headers/exhaust. The check engine light came on, no idea why...I went autozone, and this is what their computer said...So what do you guys think it is? could it be a defective oxygen sensor because i replaced the one the headers when i changed the headers...Any ideas? I don't want to take it to the dealer yet, because i would have to remove my headers if i want to get my warranty. So any ideas? Anybody had something similar?

 

Its because of the header. it removes one of the cats so the computer thinks the first one (we have 2) is malfunctioning. Search for the no-foul mod either on here or on google.

 

thats the same code i get after my header, its nothing to worry about really unless you go to get the car inspected. i have the scangauge II and it deletes the code but it comes back after a day or two.

 

i did do the anti-foul.. i guess it doesn't work for me..thnx anyways.

 

disconect your negative battery terminal.go buy the mmw now weapon r cel eliminator. 45 bucks but worth it. what header do you have btw?

 

Megan Racing Header
btw doe the mmw thing work 100% ? or could it be waste of money..cuz 45 bux is a lot.

 

ah nice header. I have the same one except from the 1st production. mine has the pre cat my cel comes on every freaking day! so sick of it.I'm gonna order the cel eliminator on th or fri. I have several frinds that have it and it works. no problemtalk to a few people on here and they will say it works flawlessly

 

how is that header? i thought those were defecive and would cause engine damage of some sort?

 

I never heard such a thing about the v1 megan header. I've had it for about 2kmiles and my friend used to have it for 10k or so. no problems

 

hhhmmmm. i dont know, im gonna try to fish up the thread i heard that in. thanks

 

i tried to install the anti fouler that came with my AW header but i guess it wasnt made to fit with the invidia spipe cuz there was no way in hell it was gonna fit so i just didnt worry about it. once i bring my car in for a resonator ill get the shop to see if they can get it in there. is this mmw one the same thing? a link would be nice, thanks.

 

Sry, I don't want to sound like I'm pushing this guys product for him, but when I see others with CEL I offer this up to them as advice https://www.scionlife.com/forums/vie...210&highlight=

It's only 25shipped, I've had mine on for over a month now, and as of today 1659 miles and no CEL yet, nor has anyone that bought one complained that they recieved one. He originally had it made for the Invidia s-pipe b/c the current anti-fouler mod would not work for us so he put a 90 degree bend on it. Well we realized that it can indeed be used for any s-pipe as the size of the o2 hole is going to be the same. Plus you can tighten it to point in the direction that you want it. You screw it all the way into the pipe, then back it out only enough for it to point in that direction then tighten it down with that nut the is on it. Hope this helps some of you out, for 25 bucks I think its a pretty good product for one of our own guys to come up with.

And to ishb3w the anti-fouler mod won't work b/c with the increased size of the piping, Invidia left the bung in the stock area but did not account for people using that mod as they don't sell a header :D I hope the above link can help you out as well, and I'm sorry you didnt find a thread that mentioned that before you spent the money on the parts for that mod.

 

I remember hearing something about a header that had the cat on it. Don't remember the company but something about the ceramic material in the cat broke apart and clogged up the rest of the exhaust piping as it blew out of the cat on the header. Usually getting stuck at the second cat on the mid pipe or in the muffler if that cat was taken out. Damaged some peoples exhaust if I remember correctly.

 

yes thats exactly what it was... thanks!

 

megan racing headers are not made from ceramic materials.they are made from stainless steel

 

the precat was made from ceramic! still have some doubt? read this thread: https://www.scionlife.com/forums/vie...megan++headers

 

We're talking about the ceramic packing in the cat that was on the header, obiviously the header is not made of ceranmics Im not that dumb
