Corsa GSi 16V

[record1]

Hi, Sorry but this technical question is not for a nova but a corsa and I hope you guys can assist.

My Corsa is badly mis-behaving, e.g. misfiring when cold and then cutting out for no reason. The car kangaroos when cold and cuts out when hot.
I recently fitted a K&N induction kit which was ok but seemed to make the
above problems worst. Please could you advise what could be wrong.
It's an N plate 1.6 16V, standard apart from the k&N and magnex back box.

Thanks

if the ecu light is not coming on (have you checked the bulb if its not) then id say spark plugs/leads.
iv got alot of spares for that engine if you need anything
