I was told I needed fuel injector service on 2005 Ford Escape

There is a cheap way and the right way to hook up to machine..what is this and how much does it cost?

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?
