hi i just bought a pinin 54reg 2.0 gdi and have a few problems, does anyone know of the error codes po125 & po170, the air filte rand spark plugs have just been removed and look like they havent been changed since the car was new, its a 1 owner car but needs lots of tlc and was only £400 so i took a chance on it but its running badly and keeps cutting out, thanks guys in advance and will much appreciate any help.
