What is your question?
How often should the fuel filter and fuel injection nozzles be cleaned by dealer. Can I do it myself?

once a year on both. unless you have the equipment, you are better off letting a shop do this service. the additives sold in parts stores are not good enough. you dont need to go to a dealer. any good repair shop can perform this service. Roy
I think it depends on the miles you drive. The injectors do not need to be clean, but the throttle body is a lot more important and should be done every 15,000 miles. The filter every 30,000.
