Is It Better To Clean Or Replace Dirty Fuel Injectors?

First some information on how fuel injectors work.

Every time the injector sprays fuel, a small amount remains in the nozzle. As it evaporates, it leaves behind a wax-like residue that forms hard varnish deposits.

Because of their construction, fuel injectors tend to "gum up" after 15,000 to 30,000 miles of driving. Fuel spraying from the injector must pass through a very small opening in the discharge nozzle. This is necessary to create a cone-shaped spray pattern that breaks the fuel up into a fine mist for proper atomization.

First we try cleaning them as this cost less then replaceing them. If this is not successful, they must be replaced. As always the best advice is to see a Modern Auto Air technician and allow us to check your system.
