Thats right. i did this non-fouler trick on my truck and it works great. I have heard of the 02 simulators notworking in some cases, plus they cost alot

 

Now wait. im wrong. you only need 2 sets..DO NOT put them on the front o2's. the front o2's controlthe A/F signal that goes to the PCM, plus whatever else they control; you dont ever want to mess with them. just do the rear o2's

 

ahhhhh ok thanks a lot. that helps and makes a big difference haha.

 

Im glad i read this post im changing my exhaust soon and i was dying to get rid of those cats...im just going to hit them with a reebar till they break forget cutting and welding.

 

I take it that you don't realize that cat's have precious metals in them, you can get some good money for them at the scrap yard

 

i saw on the package in the DIY for the non foulers i need a 18mm? i got 14mm and its clearly too small after i brought it home and compared it to my old o2 sensor and the fact that the drill bit was about the size of the non fouler.....

 

Yea, the last time I did it was on a buddies Chevy about six or seven years ago. I had the clerk at the auto parts store get a O2 sensor forhis truck out of a box to match up the size...

 

ok so it may be or not be 18mm? i just have to measure it up to my o2 sensor, which i have 1 laying around?
