Question need help with cats and o2 sensors...

Hi everyone, I'm new to this forum so go easy on me here....I'm a member on focal jet and have been reading threads about gutting the manic at on the 2.0 duratec and installing sparkplug nonfoulers on the sensors so they won't throw c.e.l. does anyone have experience with this? I need to know if only one sensor needs to be tricked or if both the 2nd and 3rd need it. And also I'm unclear as to how many nonfoulers need to be installed per sensor to get a correct reading after the cat is gutted. Any info would be appreciated.

Why do you want to do this for? You could add a '05-'07 23 st mani/cat to your 20. Its the best flowing mani/cat. to .

A good tune would probably take care of any check engine lights. I have the fswerks race header and all the other good stuff to go with it. I have 1 o2 and no cats. And with a little tuning from fswerks I have no codes and my car reads as if all is there. Dont know if that exactly helps with what your asking but a tune I would think would help it.
