Hi all, new to forum and new to the Santa Fe. I have just purchased a 2002 Santa Fe, however problems have started! Sometimes it decides to cut out, usually when you give it a bit of power accelerating putting engine under load. I had the codes read and it comes up with u0009, this using a generic obd reader. The car has FSH etc,recently serviced. Would this sort of thing be caused by fuel filter as that doesn't look to have been changed recently. Any help or guidance would be appreciated, want to get it sorted asap as apart from this the car is a cracker, thanks all
