Hi my name is***** will be glad to help. Injector failure is common on the N14 engines. first be sure the injector harness and ECM drivers are good by using noid lights to test the injector pulse/signal. They should light the noid light bright. If not check the harness or you have faulty injector drivers in the ECM. Next check for return fuel restrictions causing a buildup of fuel pressure in the injector rail and cylinder head. Let me know
