Engine jerk can be from many types of issues, Cannot just generalized the problem, and worse is your in intermittent.....

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.
