You have a common misfire. That has nothing to do with the charging system or fuel filter. The most likely cause is it's time for new spark plugs and wires. In the unlikely event those don't solve the problem, then start looking for less common things like a plugged fuel injector or low compression in one cylinder. A valve or compression problem won't be intermittent.
