I have tried everything under the sun and still get an intermittent cell. But I have noticed no difference in performance or gas mileage.

Invidia test pipe with:
Invidia O2 simulator
1 anti-fouler
2 anti-foulers
2 anti-foulers with steel wool packed in.

Check the search function. There are multiple threads on this.

 

i will be adding another anti fouler so its 3 total hopefully it goes away. Right now my CEL comes and goes. I don't think it affects the gas mileage or anything. I still hit Vtec with no problem.

 

As long as the code it throws doesn't hurt/effect the engine, I could probably deal with the light.

 

I have the Berks testpipe with built in CEL fix, it was good for like the first 6000 miles and now every 100 miles or so the CEL will come on, mostly when going up an incline and engine is at like 3200~3500 rpms, in fact if I go up the same hill it will 95% of the time come on. I have an OB2 reader that clears the CEL. I have never noticed any decrease in fuel mileage with the CEL on, I wanted to test this and left it on for about 1 week straight (normal time to fill with about 10gallons) and my mileage was right at 21.5mpg just as normal.

Looking to get KPro in the summer and hopefully it is like it was on my old 5R Teggy and you can turn off the secondary O2 sensor.

 

I threw a cell with just the invidia testpipe with cel fix. 2 nonfoulers later and the Cel cleared it has not come back on in 6 months.

 

Are they elbow anti foulers, or just straight ones?

 

2 straight ones. fouler, fouler, invidia cel fix, o2.

 

Ok, cool. I've seen that some of the Invidias come with this "CEL fix"... Is it just a typical extension/anti fouler?

 

Here is a thought that works... Find something that can filter the air but won't catch on fire like steel wool. It's out there and a couple people here in Broward have it with 0 CELs ever.

 

dang you get 21.5 mpg, thats pretty bad. I have a test pipe and the cel is on however mpg didn't get effected. I get about 26-27 mpg. On freeway only, i would get up to 29-30 sometime.
