Idk why but should i get new o2 sensors??

Help!

 

What kinda catalytic converter and O2 sensor setup are you running?

I have a test pipe and I have 2 foulers putting space between the o2 sensor and the test pipe.

 

Seems that test pipe and P0420 go together. Didn't the place you bought this setup have procedure to "fix" this CEL?

 

I think that is what is "foulers" or deflours/O2 spacers are for if I'm reading correctly.

However, if you have effectively used a defouler for 3 years I would assume your O2 sensor is gone. Clear the code and see if it is reproducible.

 

okay so I started it up yesterday on my lunch and its gone?! it came on when I was doing a 4th gear pull to fuel cut off and I bounced it off the limiter little hard because I was paying attention to the road.

Ill report if it comes back but car runs GREAT. and I heard that censor doesn't matter anyways, so imma let it be lol

 

did you talk to ballade about this problem? what did they say?

 

No I haven't ill PM them and ask.
