So i got intake installed and now my check engine light is on and it is giving me code of P0411. I have heard it is most likley vaccum lines or white check valve. Does anyone know where this white check valve is located? Please let me know if you have experienced this or may have solution to what the problem may be. Thanks in advance. In case you missed it it is Honda S2000.
