I have replaced Plugs after getting code saying Cylinder 4 misfiring. Smoothed out for about a month cleared code. A week ago the check engine light came back on and it started doing the same thing. Checked air cleaner replaced. No difference. Put car in park at stop light and the sputtering quit. Any ideas, better yet easy solutions?
