injector codes 2015 Pete 579

[tree98]

We're any injectors replaced recently or were the steel tubes that connect from the fuel rail to the feed tubes in head loosened for any reason? Those feed tubes that go through the head into the injectors need to be retorqued (with an actual torque wrench) anytime they are removed or even if you just remove the steel line going to them from the high pressure rail.

Also if you replace an injector, you must replace the corresponding feed tube, you cannot use the old one. They are a crush fit seal and become unique to the injector they are tightened onto.
