Just drilled and installed o2 foolers!
And I hope this finally eliminates the service engine light! I've got a 3" TBE with a high-flow cat and I suspect that's the problem. I've replaced the o2 sensor once before thinking that was the problem, but 25 miles later, the light came back on again!
I've got 3 miles on it since the foolers... here's to another 3,000 miles without the light coming back on!

i used the mechanical fix for the o2 and the CEl came back on after about 5 days and was having troubles so Dapper Dan patched my ecu for me to disable the rear o2 works nice! Thanks Dapper Dan!!!

Really? Tell me more about this patch... I can't afford to have another "not ready code" as we all get plugged in for inspections here. The car is a hair lower now, and I'd like to have more clearance by removing the anti foulers.
I've been running the Spark Plug Anti Fouler fix for over 50k now without a hiccup.

As far as the patch, all of tephra v5 roms (maybe v5.1...I forgot) already have the patch included. As far as the patch itself, search the ECUFlash forums. mrfred was the creator of the patch for his ROM 88590015 (Evo IX) and I ported it to my ROM, 96940011 (all 05 Evo VIII). I have a separate thread for that ROM. Just search that subforum and you will find it.

I have an older version of the patch that does throw the "not ready" code. I've been told the newer patch (Tephra/Mr. Fred) will not throw the "not ready" code, but the resistors are needed for this to work.

What the patch does is it simulates the rear O2 signal so that the ODB readiness tests for cat efficiency will pass and that no CEL for rear O2/cat efficiency will light up. You keep your O2 sensor in place.
