    Intermittent could even be faulty wiring, barely touching etc. Crank sensor, cam sensor, coil trigger wire, even o2 sensor faulty also might cause jerky... I would suggest you change another mechanic, depending on your location maybe someone can recommend a reputable mechanic around your area

    Hi there. Through my experience for this particular engine, if one coil is faulty , we need to change all of the 6 coils. Otherwise the jerk problem will reoccur . So far nobody can give me a good reason for that. Even asked a few Nissan techie last time.
