you should search first...I guess everyone is in a good mood answering your question

9,000 people have had this issue and you obviously were too lazy to check first

 

yep best way to do it. easy n cheap. worked 4 me

 

I recently installed a 3" TB exhaust i used the o2 bunghole in the cat back rather than in the cat delete pipe...............the cell light came on after 50 miles......so i did the 'ol spark plug anti-fouler and 60 miles later..........NO CELL.......that cool trick seems to work well.

 

yeah the spark plug non fouler is def the way to go to keep the cel off

 

 

+1 on the non fouler. However, you're going to need a tune as well. Under normal driving, my car was fine with TBE and no tune, but when I would drive it hard, I would get a pretty harsh boost cut at about 6k. Like everyone has stated before, this is a common problem.

 

Post some pics of your exhaust!

 

old topic but oh well

2 spark plug anti-foulers (18mm). It is made by the HELP! brand part#42002 or 42009

 

If the wire to the O2 sensor in the cat were cut, could it still be wired not to throw a code?
