Need help. Have 02. Check engine light comes on and off. Loss of power, black smoke whether driving empty or hauling. Anyone have an idea? Fuel pump in tank? Fuel pressure regulating valve? Fuel pressure regulator?
what year truck you have? Normally with the LB7s (at least in my experience) when you get the overboost code it just trips the light and you dont lose power...but I know there are some that do lose power.
