Thread: weird stutter after 1.8 rr install

Know someone with a tuner? Have them set p0420 to no report and you'll pass just fine

I have the stock pcm in now that's why I get that code, its failed with with both pcms, I have a overkilled pcm but its a little rich around 14.4-.5 afr so I put the stock pcm in and it still failed so its either my cat or my egr I think
