a good inj clean should cost approx 150.00 depending on labor rate in your area
Don't modern fuel injectors' have fuel with detergents running through them. What symptom are you addressing? Why do they say you need to clean something , that when in use , always has a cleaner(gasoline) running through it? How many miles on vehicle ? what other maint has been done?
