The antifoulers and mil eliminators don't work for all tC's. I had to relocate my secondary o2 sensor behind the cat. If you have stock exhaust relocate behind the cat on the midpipe. Why does everyone show STD correction factors and not the SAE numbers. What was the SAE numbers

Just FYI curent car's with OBDII have to o2s to check how much oxygen is in the exhast befor the cat and after it passes though the cat when u elimiat the cat the computer knows its no there because the voltage from the O2 dosnt change at all thus trigering a CEL the antifouler , O2 stimulator or whatever u place inline with the O2 to fool the computer into thinking the cat is still there i would sujest to any one not just peple with schions out a high flow cat it dosnt give up as much power as they use to and the air will be cleaner and no CEL

If you have the antifoulers and are still throwing a cel here is a good (FREE if you still have the stock exhaust manifold) fix.
1. Knock the catalyst out of the manifold. It will come out in big chunks.
2. Take your two antifoulers apart.
3. Cut a piece of catalyst to fit in the antifouler. Be careful not to make it to thick or you will smash it when you screw the two antifoulers together.
4. Install back into car.
5. Reset check engine light.
6. No more cel.
**This modification is only necessary if you already have the antifoulers installed and are throwing a cel**
I have had to do this in a couple of different vehicles where the antifoulers did not work. I have yet to have any cels after doing this. I can not guarantee that it will work for everyone else but for the cost it is worth a try.
