P0455 & P0456 ON FG2

Post by sameer25 »

So I have an FG2 (2007 honda Civic Si) with the stock K20z3 and a turbo. I have all the EVAP options disabled in my misc options. The car is fine for a while after flashing it with a tune but after a week or so I get a check engine light for P0455 & P0456. The code goes away when a reflash the tune but it's annoying having to reflash it every week. is there anything I could do to fix it? I do have all the EVAP/Purge related toggle boxes checked off
