When does it misfire? Under load, just on idle? Have you tried the car with the proper airbox back on? As from what i've seen induction kits bring nothing but trouble, especially on the 1.2 16v engines.

Does it do it everytime, or just when engine is cold? Personally i'd get the airbox back on and go from there, see if that makes a difference.

Induction kit won't be helping anything at all anyway and certainly won't be improving anything.
