How TO: CEL/MIL Eliminator!
- Thread starter acidbug
- Start date
After several unsuccessful attempts with the MIL fix from Apex with my header I finally gave up and went with the spark plug anti-foulers (I think that's what they're called). Been a couple thousand miles now without a CEL and no MIL fix. Wish I had gone with this in the first place so I wouldn't have had to cut my O2 sensor wires.

can someone please elaborate on the other way to do this without citting the wires, using the ant-fouler thing? Blaxer, do u have pics at all? Id prefer not to cut my wires but i will if needed. im getting the obx header off the group buy. Will the spark plug ant-fouler work? i dunno even know where or how this thing would work..im a total newbie to this idea. thanks for any help people!

It wont. Simply moving your 02 sensor out of the pipe a little is going to do nothing for eliminating a CEL. That trick is to free up the flow of your exhaust by having the 02 sensor not sticking into the path of the airflow. I have antifoulers on both of my 02 sensors. My 02 sensors are completely out of the flow, back in their own little "pocket".
If antifoulers stopped CEL's then I would not have one would I?

gotcha, thanks for the quick info...sorry for the dumb Ques.

I guess I dont see how in the world moving your 02 sensor out of the exhaust flow slightly, is going to "trick" it into thinking that all of a sudden the cat is back and the exhaust is all nice and clean now? Its not going to send back the correct milliamps that is made when it is heated up and "sensing" the air / fuel mixture that is unburnt in the exhaust. But if it worked for you, than more power to ya.
There are always unexplained miracles in life. This may be one. Another is that fact that anyone would buy anything made by GM

Yeah, I wish I understood why it is working for me, but I don't. The MIL fix is easy enough to understand why it works, but this I don't know.
Oddly enough, my other vehicle is a GM
Edit: Ok just checked the NASIOC board and found some relevant information. The O2 sensor voltage output is directly proportional to the temperature of the filament. By using the anti foulers you effectively remove the filament from the hot exhaust gas flow lowering the filament temperature. When the temperature is reduced the voltage output of the O2 sensor is reduced, simulating the output of the O2 sensor in the exhaust path, with the cat installed.

Ok! Finally got my header installed today, and on the way installed the CEL fix, thanks Chas!!! Although, seems like my gas goes away pretty quick!!! Yes I did reset the ECU. I hope my ECU will learn QUICKLY otherwise I will hate myself to fill up every 3 days (as Im driving an hour to my job). Well, Ill see what happens in 2-3 gas tanks.

NO CHAS!! You just spoiled everything!!!!! (rofl) You have to say that gas milage will be increased! (rofl)
Man, thats bs, I saw my 1st quarter of tank go in freaking 3 hours, not even gunning it all the time.
