Amin, just pm'd you!!
There is seemingly no fix for this common issue. I've tried every adaptation known to man, injectors, coils, plugs, head decarb and have never fixed the problem.
I got an improvement when I replaced all injectors and double checked plug gaps but it still has a slight idle hiccup which will bump up the revs to 750 rpm after a minute or two on idle. I made a decision to live with it and move on many months ago and I suggest you do the same as you'll end up very frustrated and massively out if pocket chasing it!
