do i need fuel injector flush
My car has 160000 miles.
My car has an automatic transmission.
If you have never had the fuel injectors service or you are having problems that need the injectors flushed then it should be done. If you are not having any problems then running good fuel and additives in the fuel tank to keep the injectors clean will keep them clean. I would recommend having a mechanic like one from YourMechanic check the engine for you if there is any running problems.
