Then Engine Light code is P0301 - Cylinder 1 Misfire Detected - Cylinder 1 Missfire.

Initial Resolution:

Changed Air Filter $14
Added seafoam S11
To the oil change ( Semi Syntetic Castrol High milage) and gas tank to clean Oil and Fuel reladed components.

Problem has not reocurred.

Will change spark plugs ( Platinum 2 for $10) @ 100000 mils to elimiate one electrica componend.

Try those resolution first before following the Nissan Help sugestions of Replacing more COSTLY PARTS!
