So im removing my cat this week and since i have a 96 i need to fool the downstream o2 sensor. Do i have the process correct?

Remove 02 sensor

drill out 18mm spark plug anti fouler to .5in?
thread on fouler
put on second fouler with anti seize

nice find. i've also heard that you can just ziptie it on the frame somewhere and since its reading clean air it will be fine

 

I've heard that too and just put a plug in the old port. I have the non-foulers on mine and haven't had a CEL since.

 

My cats been hollow for the last year. I rarely get a CEL. I might get one once every couple months if that. I just clear it and continue driving. I have yet to do anything with my O2 sensor because of that.

 

yeah, good chance that its just dirty and not gettin a good readin......
