Most likely if you feel it is vibrating a bit too much then I would have to say run some fuel system cleaner with alcohol to remove and water from your fuel. Other than that if there is an issue it should throw a code with so few miles any other symptoms? Good luck.
A good way to make it not so obvous is to drive faster.
