If you used Bosch platinum plugs by any chance, replace them with the proper type NGK's. Stick with genuine Nissan or NGK when it somes to ignition parts. How is the distributor cap & rotor? Fuel injectors have been known to cause misfiring on the VG33E engine; Nissan recommends a professional-type fuel injection service prior to replacing any injectors as it usually fixes the problem. Have you tried checking for stored trouble codes?
