    CAUTION: Two different fuel injectors may be available, a 49 state fuel injector and a California fuel injector. These fuel injectors MUST NOT be interchanged, as Powertrain Control Module (PCM) is calibrated for specified fuel injector. Before replacing any fuel injectors, refer to Vehicle Emission Control Information decal for proper fuel injector application. Decal is located under hood. Improper fuel injector application may result in poor engine performance, high emission levels and/or damage to engine.
