lasermp5 said:Good write up. Would have helped me out a lot way back when I didn't know wtf a non-fouler was. People eventually explained how to do this, but this will make it far simpler for others in the future.
Rac3rX said:How did it go?
SlowPro98 said:Not good. The donut gasket was shot, and no one in my area had one ( 4 part stores and 3 websites later) so Ive got one on order, and Im still waiting for the stealership to get back to me.
But taking it out was pretty easy. If anyone needs the special socket to remove their 02 sensors, Hit me up, I picked one up, worked like a charm. Id rather pay the $26 for the socket than the $100+ for a new sensor after stripping the threads.
The non-fouler was easier than taking a dump. Hopefully Ill get to test it by the end of the week. For now, Im rollin in my wifes car.
Rac3rX said:How much did the new gasket cost???
gbean said:Did you not tap the threads on the part you drilled out?
If so isnt that kinda shade-tree stuff. I would be tapping that!
Rac3rX said:Why, the non-foulers are already threaded, and the o2 sensor sits in it like a chamber screwed to the non foulers thread then the non-fouler goes in the place of where the o2 sensor bung is.
You drill it out so the o2 sensor can slide in, no aditional threads needed
gbean said:Sorry I was looking at the wrong part. i am an idiot.
I see how it works. So by letting less air flow to the O2 sensor it thinks it is running right based how much air it knows it passing through the exhuast?
So how is the mixture then supposed to be adjusted for other variables like altitude and humidity?
Rac3rX said:Basically the First o2 Sensor that is Pre-Cat is what Speaks to the ECU.
The Second o2 sensor is what the non-fouler is installed on when a header is installed. Installing a header removes the first Cat. The 2nd o2 sensor does only 1 thing, Verrify that Cat 1 is working.
Your corect The non-fouler creats a chamber outside the direct exhaust flow reducing the emmisions it receives, tricking the o2 sensor into thinking the Cat is working. It send back a good reading and all is well.
All in the while o2 sensor 1 is comunicating with the ECU as if the 1st Cat is still there.
gbean said:Thanks for the quick reply.
Makes perfect sense.
Now if only Headers were not so expensive.
