Afternoon, my 1976 280Z 2+2, has shutting down issues, I will be driving alone at 50 MPH and the vehicle will just shut down and immediately fire back up, I guess you could say it hesitates, I've replace the Elec, fuel pump, the fuel regulator, distributor cap, rotor, plugs and wiring all needing replacing anyway, any suggestions on what cause the engine to hesitate and immediately fire back up, could it have anything to do with the reluctor adjustment? any assistant and/or suggestion will be appreciated.
