Test the systems before replacing parts, will save a lot of money this way. Test the fuel pressure. If OK check vacuum system for leaks. Check PCV system for proper operation. Many things to test for a misfire code so its very very difficult to guess at a part and replace it to fix the problem. And the fuel filter is not going to cause a misfire in only one cylinder
