Hi there,
This is a sign of coolant in the combustion, you will have to get a head check done for a head gasket problem or there may be a problem with an inlet manifold if it has a water passage, the gasket may be blown and coolant is entering the engine via the manifold. If it is running rough check for a head gasket problem first.
