yesterday after waiting for two weeks for getting a new rear O2 senor i put my test pipe on. went for a drive and really love the sound with invidia v3 cat back and now invidia 70mm text pipe with cel fix but it is loud. well after about 15 miles the cel light went on, so i had the codes read and its all the secondary 02 sensor. i dont want to look at the cel thats why i got the one with the fix on it. so what do i need to do for it to go out and say out. right now i have rest the ecu for it to go out but havnt driven it. any advice or help would be great

 

I have the same problem. I have the Berk Test Pipe, but I still have a CEL.

The only solution I can think of, is to buy an Anti Fouler at Auto Zone.

 

Buy a couple of them. I have an 06+ s2k and it is really finicky with aftermarket testpipes. As of right now I have 4 spark plug anti-fouler and the built in CEL fix from the Berk's testpipe.

 

tudernos, do you have have the cel light on???

 

hfc, no cel, costs a bit more and gets 1whp/1wtq less than the tp...

 

Yeah... I have 4 spark plug anti-fouler with the CEL fix on my berk's testpipe and I still throw a CEL. Oh well... I tried but I think even if I were to add more spark plugs it would still throw it off. I guess the only way now is to get a HFC or put back stock but it doesn't bother me with the CEL on.

 

If I threw a CEL and put on the anti-foulers a few weeks later, do I need to reset the ECU to clear it, or will it possibly clear itself after 50+ miles?

I'm at 2 anti-foulers tudernos, hopefully I won't catch up to you anytime soon... or else HFC it is!

 

No CEL on my 2006 with Berks HFC.

 

i bought the berks tp and got the cel when i first got the car. i was wondering something though...

does having a cel on void the factory warranty? would they check for anything like that?

 

Did you reset the ecu before you installed it? Try the reset, if it doesn't work, go grab some anti-foulers. for another roanoke s2k.
