I have have straight pipes on my car. FVD tune etc. Been on for about 9 months. Never a code. But I am having to drive it to work the past 2 days. So I have been in heavy stop and go traffic. And that is whe the codes popped.

Here is what I get from Durametric. Is that O2 sensors on only one side? Can they be cleaned or just replace them?

AND is there a link out there with all the codes in one place?

its O2 sensor for each side. you likely need the post O2 sensors turned off or use O2 extenders.

Like have them turn off the O2 sensor reading?

And why would it ONLY appear in slow hot stop and go?

Just trying to understand.

Yes your tuner should be able to turn them off.

the pre O2 sensor reads exhaust gas. post O2 sensor has to read a lower level of exhaust gas or it tosses a code. have your tuner shut off the rear or post O2 sensor if you dont need to pass emissions. or use j tubes if you do.

Big Daddies Garage spacers work perfect for this without having to code out.

Interesting that you're seeing the codes after 9 months of no issues. I have seen these codes before, but that was before my custom tune was finalized for my 'off-road' exhaust.

I would call FVD talk to them....
