It sounds to be a fuel system fault, look into your fuel injectors and your fuel pressure reg, it sounds like there is a possible failure in there.

Hi. My fuel pressure reg was replaced last year. Injectors have been cleaned with special fluid car still the same. I think my fuel pump makes a constant whining sound now! My black fuel vent valve in the engine bay has recently starting making a ticking noise after the car has been start for screw minutes. Thanks
