I used pb blaster, wd40, and liquid wrench and with a little muscle I stripped 2 of the 6 edges

I'm still going with user error.

BTW you can get an O2 wrech at PepBoys or Autozone for cheap.

I followed the link to the s2k forum, and they have some ideas to maybe fix this if the CEL returns,

"1. 70mm invidia tp w/ built-in fix on stock exhuast (ap2 '07)
2. added external spark plug defouler fix (ebay one piece deal)
3. packed steel wool into the external fix
4. added header wrap to the tp - to stablize temp around the 02 sensor "

I'm planning on adding some steel wool when i have time this week.

Does anyone have any other suggestions?

How would i know if the code is caused by too LOW or HIGH exhaust flow to the sensor?

Did you drill out both foulers or just the one around the O2?

I just drilled out the one that the sensor is screwed into.

Still haven't done any work on my car yet

Update

I started my car today after not driving it for ~5 days. The CEL did not come on. I idled it for awhile, then took it out for a drive. ~12 min total start time, no CEL. Was ok at normal operational temp too. Restarted x 2, no CEL. Maybe things are working out ok after all

i have a 98-base with 176k, have had a casper's o2-sim on it for 5 years. It failed once and they replaced it about 4 years ago I think.

Now I'm getting a CEL and codes: P0138 and P0136, both Bank 1 Sensor 2 trouble codes.

I'm starting to wonder if the o2 sim is failing again. The sensor itself is at least 5 years old and I never replaced it while I've owned the car. My stock cat is gutted.

Where can a new o2 sim be had?

Awesome info..i need to do this as I am getting the CEL for this. I have a test pipe. I am going to the parts store right meow!

...and advise for those of you who are having trouble getting your o2's out. Heat up the o2 sensor bung with a torch or something very hot and then use vise grips to get it out. This is what I had to do. I tried everything...even a pipe wrench and I just stripped my old o2 sensor into a perfect circle.

Did this and it worked perfectly no CEL light for a couple of days

rayslude · 07-19-2009, 07:36 AM

for those still wondering what an o2 socket looks like...

dontbuyprelude · 01-02-2010, 06:01 PM

ok i dont think i need to start a new thread even though this one happens to be a "few" months old. but i would like to confirm that this spark plug non fouler thing works. i gutted my stock cat and drilled out one nonfouler. i left the other one alone and assembled as shown in pics and no cel for about 50-60 miles with a lot of WOT. and it seems as though 4th pulls harder. im waiting for teedots sharp criticism.

Artifex · 01-02-2010, 09:26 PM

Yes it works; there are 100 people in this thread who did it. Why would you think otherwise?

dontbuyprelude · 01-03-2010, 02:53 PM

before i gutted i was nervous about doing so. i wanted to be sure id get no cel. so maybe my little story would help someone make an "informed" decision about it.

By driving the car until it reaches operating temp. the sensor will come out easily with a O2 sensor socket (22MM/7/8").

Also for those of you having clearance issues with two foulers - buy this instead it has a 90 degree angle to it
