misfires are caused by many things and changing stuff doesn't help cause you don't know what it does. a vacuum leak, a partially pugged fuel filter or a lean out condition will cause all of this. it's best to have a pro check it and find the cause...... you could have a an injector that doesn't work right but you relally need to get it checked out..
