I hear an engine tick when I drive up near a building wall (drive thru lane) with the window rolled down. I would expect that it is probably the high pressure direct injection pump located on the fuel rail. Even though this pump has a foam rubber cover, the base '18+ Mustang GTs have large engine covers that provide additional noise attenuation. Obviously this cover was deleted for the 2019/2020 Bullitt.I am just curious if anyone has reported any of the engine tick issues with the 2019 Bullitts? Seems like there are tons of posts on other sites regarding this problem with current G6 GT owners.
