I would suspect your problem might be ignition related. With that many miles on the car, it's recommened to replace the following ignition components:
- Distributor cap and rotor. Buy only OEM from a Nissan dealer.
- Ignition wires. Buy an "NGK Blue" wire set; it's better then OEM.

You're better off to use the standard NGK plugs BKR5E-11 instead of the platinum plugs. I've tried platinum and found the standard plugs work better. Also the 0.044" gap is too large. The proper gap is 0.039 - 0.043".
