I wonder if it is the air and fuel filter.



If it was the air and/or fuel filter, then I would think that the "jerking" would happen at other times as well (besides when climbing a hill).

Besides that, the air filter is relatively new (since it was changed a few months ago), and the fuel filter was replaced last year.
