The injectors are covered for 7 years or 200k miles. If there is a injector problem, it should be covered. Ths cost for this repair would be around $4500 if they were not covered.

You my have to pay a diagnosis fee to make sure there is a problem, but if the injectors are bad they will not charge you this fee. They will ask you for this fee so if the injectors are not the problem, there tech will get paid for his dignosis time if you decline any repair that is not covered.
