Answer 1
YOU MAY HAVE AN INJECTOR ISSUE OR SOMETHING ELSE SEEK A DIAG FROM YOUR MECH THIS CAN BE CAUSED BY MANY THINGS. DO YOU HAVE ANY CODES. -
Comment 1
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 -
Comment 2
COULD THE WETNESS BE WATER FROM POSS HEAD GASKET. HAVE YOU EVER OVERHEATED THE MOTOR? -
Comment 3
I have never over heated the motor. I bought the truck 4 months agow and have put over 2000 miels on it. -
Comment 4
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. -
Comment 5
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. -
Answer 2
i had the same problem and i changed plugs,plug wires and ignition coil and it fixed it. -
