well a misfire could be from several different things (spark plugs, wires, fuel injectors, or rarely just not timed right spark plugs and wires should be switched ever 20k-30k in miles check your owners manuel and wires to if its been longer i would recommend switching both of them and as for fuel injectors you should add fuel injection cleaner to your tank approximitly everytime you have your oil changed
