I have the 2.3 ecoboost mustang. And I noticed the idle when cold or warm the car has a ticking sound, some people claim the ecoboosts have a high fuel pressure and the fuel lifters are loud but its all normal. does anyone else notice this in their ecoboost engines? if so, has anyone confirmed the claim that these fuel lifters are loud and its just normal operation? The service manager at the dealership drove the car, said there was nothing wrong.
