golf r32 with lean misfire at idle rpm is @ 600 instead of 750 or 800

What is your question?

spark plugs and ignition coils changed, fuel injectors cleaned,no vacum leaks. Misfire some times goes and the car at idle gains back its normal idling but as soon as i drive again the misfire is back with rough idling and hesitation the shaking in the engine is mild but the car seems it has lost a significant power especially at pull up. the computer is not showing any faults and the diagnosis @ the VW agency showed nothing
