How do u fix a misfire
If your truck is overheating!!! Then check the upper radiator and lower radiator hose's , if the lower is cooler the the upper the either the thermostat is not opening or the radiator is clogged
I don't think it is coolant. It is just condensation caused from high humidity and the cold air. If it is coolant it should get on the floor and you should loose coolant.
Misfire is caused when a cylinder doesn't ignite its fuel mixture. Suspect a bad plug, coil, or wire. This will not be caused by a mass airflow sensor, that can cause a rough idle or bad fuel economy, but will not cause an individual cylinder to misfire. Driving with a continuous misfire condition will eventually destroy your catalytic converter. If your check engine light is flashing you are doing serious damage to your cat converter.
A basic tune up with spark plugs, ignition wires, distributor cap, rotor, air and fuel filters then go from there.
Have you tried replaceing or checking your gas cap??
change it

I'm not sure if they are the same or not, but I had the same problem with a 2000 Ford Ranger. The fix given on another web site for the Ranger is to spray the door latch (in the hole on the edge of the open door that mates with the latch device on the door jamb) with WD40. If the Expedition system is like the Ranger, the light switch is in door latch & WD40 will fix it for a few months, at least. Hope this works.
Start with a complete tune up including spark plug wires.
