I am struggling to find the cause of a misfire on the wifes 320i Vert.

It feels like its running on 5 cylinders with a kind of chuff sound albeit very quiet.

I have changed plugs and leads, checked rotor and dizzy cap and the only thing I have found a tad odd is that number 5 plug doesn't smell as strong of fuel as the other plugs. It is definitely getting a spark there.

Anyone got any idea of what to check next?

Are both the valves closing completely?
