Time for an o2 simulator, any OBDII car will throw a CEL after installing a test-pipe.

 

from Berk's website on the berk test pipe

<2000-05 HONDA S2000 Cat Delete Pipe w/ Built in O2 CEL Fix>

* Built in mechanical O2 CEL Fix
* 100% bolt on, no cutting, splicing, hacking, etc.
* Fully Polished SUS304 Stainless Steel Tubing & Flanges
* Mandrel bent 2.5" Tubing
* Includes new 304 stainless hardware and rear gasket

This is the world's first bolt on S2000 cat delete pipe with a built in O2 CEL fix. The O2 fix pulls the oxygen sensor out of the exhaust stream so that the secondary oxygen sensor sees the correct O2 readings for a the secondary catalytic converter efficiency.

 

Thank you ALL guys! Berk test pipe will arrive on Thursday.. Ya Hoo~

i bought that anti-fouler and installed it but my cel light is still on? did anyone have a cel even with the fouler on? thanks for the help!

 

sometimes you need more than 1

 

I take that back, because few dollars (Spark Plug Anti-Fouler) just solve my problem in a min. If CEL not coming on again, I think that would be OK. Thanks guys

 

did you reset your ECU and clear the CEL after you installed the antifouler? if not, do this first and then see if it works. if it still doesn't work, you may need to put another one on there.
