Even if there is no leak on the filter it can still allow air in (don't ask me how, it just can!). As soon as I replaced my fuel filter several thousand miles later my issues totally disappeared. Don't rule that out. I found my idle was unstable only after a restart say 10-20 mins later when the engine was hot. When cold it would never do it.
