Your last sentence amazes me. You can't understand how something could cause a problem because it never did before? That can be said of every problem on every car, van, bus, and airplane since the beginning of time. Well, except for those problems that came pre-installed at the factory.
The parts you listed are all over the place so I can't use that information to figure out exactly what is happening. Is the jerking in the steering wheel? Do you feel it in the seat, and entire vehicle, when trying to accelerate? Does it occur when just cruising at a steady speed? If so, at which speeds? Could this be related to the transmission and shifting? Do you feel one "bump", a vibration, a wobble, etc?
If this is an engine-related problem, please list the right engine size so I look up the right systems.
Also be aware diagnostic fault codes never say to replace parts. If you list the exact code number you got, you'll see it only indicates the circuit or system that needs further diagnosis, or the unacceptable operating condition. Please list that code number if you remember it.
