Hi everyone,

I just purchased a used 2004 TSX hence I join this community. I have been driving it around for 2 days, and ever since the first day I filled in my gas tank, I have driven for around 120km.. and it is already at half of the tank, I have absolutely no idea about past maintenace history although it seems legit since it is sold by acura dealership directly and certified. There is no light on at all but possibly some flapping noise when I drive above 50km, any idea which component I should get it checked?

Thanks!
