Well I installed the non-foulers in my car and my to my surprise i got the CEL again

So does anyone have any other ideas or ways that I could fix it? I was thinking of maybe putting some sort of fibers like steel wool inside of it...

 

Not a good sign. Disconnect the battery overnight.

 

what year car?

 

Over night? I did the ECU reset trick. It's an 06.

 

make sure you use 2 non foulers on each side. if you didnt do this, and dont know what i mean feel free to pm me for more more info.

 

Looks like this.

 

Yeah, thats exactly what I have put on my o2 sensors, yet I'm still getting the CEL light.

 

SAME thing happened to my car last year (2004 Z).

My Fix: replace a burnt up O2 sensor ($230) and put on stock cats again.

Never running test pipes again.

 

i had an 05 revup with non foulers and it was perfect. stillen tps and same setup as above.

 

Did you really burn your 02 sensors? Huh I've had mine on for about 2 months, would you say thats long enough for me to have been able to burn the sensors?

I did have like 2 days when the CEL didnt come on after installing the Non Foulers

 

i have an 06 and had same problem. non-fouler didn't work.

 

Mine are going strong almost a year never got a CEL

 

It seems like alot of 06's have this problem from what I've read I think i may just get some HFC's.


Anyone want to buy some Ichiba TP's

 

I don't want to see you throwing your money away attempting expensive fixes that fix nothing. If you have a code what is it?

 

Eh...I have the non-foulers on my 06 Z as described by gothchick. I have had no CEL yet.

 

I'm not exactly sure what code, I just got the CEL light right after I got my TP's installed so i'm pretty sure it's from that and I put my Non-Foulers on, reset my ecu and 2 days later I got the CEL again.

 

AutoZone will read the code for you. That may help with diagnostics.

 

ya check the codes, it might be another problem besides the o2 sensors. like^ said go to autozone and have them read the codes.

 

im throwing codes on mine too got mine checked and its the back o2's on both banks dont recall the codes exactly i just left that ish alone. I get it checked periodically to make sure there is no more though. and im running none foulers too

 

came to the conclusion that w/ the non foulers the o2 sensor heaters are overworking themselves to get to their temp and without the catalyst to heat them up normally they constantly run their heater circuit which eventually goes bad. i have an 06 and ran the non foulers for about a year problem free then it threw a code for bank 2 sensor 2 heater circuit and 1 month later threw the other side. i'd just leave it alone and check the codes every now and then but i have access to a scanner at work so don't know if thats what you would want to do i just to it to make sure there are no other codes present. i guess you could try to move the o2's higher up stream to get hotter faster or just keep replacing o2 sensors!
