looking forward to passing inspection REALLLLY soon. And the car has had test pipes for about 2 weeks and then suddenly i get a code. so i didnt have anti foulers on at all and then i put one on each and the code is there and then 2 days later i put 4 ( 2 on each side total) and it is still there. i hope the o2 sensor is not gone. let me know if theres soemthing i must do thanks,.

 

Never heard of anyone adding non-fouler to the pre-catalytic converter sensor.

 

Ecu reset then drive it for a few days. I was that the foulers doesn't prevent CEL. But it does reduce the amount of times it comes on.

 

its on the catalytic converter. the weird thing is its an 03 and heard they arent supposed to throw a code from test pipes.. :\ Help.. need a solution asappp

 

^^********! lol, I have non-foulers on my cats and my cel has been on for a while now. When I took the censors out a while ago to replace to pass inspection they were all burnt up
