Hyundai Getz managent light on at times and misfires

Hi, just to share, acording to ur situation there might be a water leak from the cyclinder head gasket into the combustion chamber that causes misfire an the same time unstable combustion wil cause the light on and you wil notice that water that came out from the exhaust pipe..cn monitor the cooling tank does it often require top up of water or coolant...if that's is the case mostly ahve to perform engine top overhaul... Thks!
