Fuel Injector: Service Precautions

***WARNING FUEL INJECTOR CLEANING TSB #NTB94-002

Due to the introduction of contamination resistant "pintle-less" fuel
injectors, Nissan no longer recommends using fuel injector cleaners
in vehicles with injectors of this design. Use of fuel injector cleaner on these vehicles, while providing little cleaning benefit, may cause corrosion of the fuel injector coil and eventual failure of the injector.
Do not use fuel injector cleaner on this model or subsequent models with "pintle-less" injectors.
