First of all why would Ford have a recall because you have an engine misfire? The coil pack and sparkplug on cylinder 4 may not even be your issue since it was changed. A bad fuel injector can also cause a misfire and give you the same coil. As far as cool and consumption they only cause of this is a leak in the system. Faulty water pump or head gasket can be caused of the leak. At 95,000 miles this sounds like a common maintenance issue for any make or brand automobile. Have a competent Ford mechanic diagnose the issue properly.
