But seriously, those three are not always the cause of jerking.
You can break this down to two possible groups. The ignition system and the fuel system.
You said you're always out of the country, so I'll go out on a limb here and say that you probably have shellacked throttle body and injectors that need cleaning.
Of course having your car diagnosed at the dealership will give you a better insight of what is wrong with your car.
And if they suggest that you change your fuel pump, ask them for the fuel pressure reading. If they can't tell you what the pressure is, then they're just guessing. The service manual states that the fuel pump pressure should be within 284~325 kPa (41~47psi).
