I always went straight to 234 on decel in my lambdas with my old injectors ,i recently updated to index 12 and they used to do the same. I found a crack in my valve cover and fixed with epoxy while im waiting for new one. I also ordered new plugs and the new black r8 coils that panzer showed us. So I setup my logging tablet and neither of my lambdas close out steady on deceleration. Bank 2 hits 234 randomly but bank 1 hovers around 200 , does anyone have any clue how this is or could multiple index 12 injectors from I buy auto parts have shit the bed in 3k miles.
