Coolant smell means there is a leak somwhere. If it is inside the cabin, the heater core could be the cause.
Get a pressure test performed to locate for leakages. If it is a head gasket problem, the recovery tank would be increasing in level whereas the radiator side would be depleting.
When the MIL indicates, it means an error hads been detected and you need to retrieve the trouble code to find out what is causing it. The trouble code would enable us to know if it is related to the misfiring.
