So recently I have deleted my resonators, and when i put back my exhaust i didn't put back the Exhaust Gaskets (because they fell apart) that are from downpipes to exhaust. Could this cause air leaking in to my exhaust system and giving me that code?

p114d - post catalyst fuel trim via oxygen sensor system too lean.

thank you

I’ve been getting the same code after installing a full car back exhaust saying that bank 2 is too lean I’ve replaced the sensor already and the precat sensor has already been replaced I think it may be a because I installed the new exhaust it hasn’t the performance in anyway but it’s still annoying to see the EML light I’m just considering deleting the both the sensor because I’m sick of them

Yes, obviously not putting the gaskets back will make it leak. Get some new ones from VRSF or similar and you'll be back in business
