How-To: Trick Comp From no cat
Parts Needed: ( 20 dollars if u dont have bits or compressed air.)
18mm Spark Plug Non-Fouler (come in 2 per pack)
Avail at local auto store (5 bux)
7/16th drill bit (5 bux)
Compressed air (outta can will work) (5 bux)
7/8th wrench (o2 socket will not work) (5 bux)
Drill
How To:
Jack up car
locate 2nd o2 sensor harness and disconnect
Grab 7/8th wrench and remove sensor
Take non fouler out of package and secure (preferably in
a vise) and drill out the inside of the non fouler. (if u try
to screw in o2 into non-fouler ull see y) just a bit needs
removed. DO NOT GO ALL THE WAY THROUGH THE NON
FOULER. You just need to open up the inside of the non
fouler so the o2 will fit inside it.blow out shavings with air.
Screw in o2 into non fouler then install non fouler into o2 bung
* May not work if u dont have an extra 3/4" of clearance around o2 sensor, u can get an exhaust shop to install an extra o2 bung if u need the clearance and u can plug the extra bung with an oil drain plug of m18x1.5
With this mod the o2 get heat for the heater circuit still reads a minimal amount of exhaust (just the tip of o2) making it seem to the 02 there is a difference from o2 #1 t o2 #2.
here is where u bore out the inside of the non fouler the circle in yellow needs to open up to 7/16th so the sensors probe will fit inside.

I think it's just supposed to trick your car's computer when you don't have a catalytic converter anymore......when you take the cat off....it'll throw a code.....this mod I believe removes that code, and fools the computer into thinking you have a catalytic converter still.WiTeOuT wrote:So forgive my obvious ignorance. But, what is this Mod supposed to do again??? And what do you supposedly gain?
Please keep in mind that removing your catalytic converter is for OFF ROAD USE ONLY

And for the records, if you do this mod correctly it WILL eliminate the Efficiency failure code. I have been on mine now for over a week (put 80 miles on a day) and NO code.

true enough. code 420 finally popped up for me after about 2 weeks of running with no cat. I think i'll just run it rich for the time being until i can get a wideband hooked up though.

you're probably getting a combination of 0139, 0140, 0172dawm wrote:i got my foulers gonna get it drilled out at work prolly sunday or monday. had a CEL from O2 reading too rich heh so we'll see if this works =P
your 'o2 sensor reading rich' (0172) has nothing to do w/ your downstream sensor
with your downstream o2 sensor disconnected, you should get a code like, 'o2 sensor 1/2 remains at center' (0139 and 0140)
