    No the check engine light is not on and I dont have any codes. When I pull the plugs some of them are wet after the truck has been sitting for hours

    COULD THE WETNESS BE WATER FROM POSS HEAD GASKET. HAVE YOU EVER OVERHEATED THE MOTOR?

    are you using small amounts of water in your cooling system? i suspect a head gasket issue you may want to have that tested. the veh misfires until the water in cyl burns off then its ok till it sits for some time.

    What does the 'wet' smell like?.....GAS? Is the crank time extended? did you put the correct ford IRIDIUM plugs in it Check label under hood , usually emissions control label , will give spark plug type (or OWNERS manual) Sounds to me like it's starting slightly flooded then clears up. Try a "clear-flood" mode start... Press the gas pedal to the floor and hold it DON'T pump.THEN turn the key to start it while continuing to hold gas pedal to floor . As soon as it catches (starts) let go completely of the gas pedal. Any difference?If not , then at least I didn't injure any fingers while typing! good luck.
