I had the injectors on the right side replaced at 320000 miles because of a code p062d. The code came back at 331000 miles it’s at the dealership again they are replaced the right side plus one on the left. Is there any reason why the injectors would be failing so fast? Has anyone had this problem? Truck has had the fuel filter replaced at last oil change. Truck is all stock and serviced at the dealership all it life.
