Missfire on idle

As above, have been chasing the same problem for ages!

Have changed lambda sensor, spark plugs, coil pack, still doing it.

What else could it be please?

Plug leads?

i suggest you get a diagnostic machine plugged into it rather than guess work. much quicker and accurate way of finding out
