Since 2003 ECU Code P1456. Damn Acura dealership could not fix it. They tested the fuel and vaccum lines. Acura replace purge canister valve, 2-way valve. That did not solve it. Me and my friend swap gas cap for 3 weeks that did not help. There is no pressure in the gas tank cause I don't hear the hiss noise when removing the gas cap. I can't figure it out.
