I didn't think that the plugs back themselves out. I thought the first torque spec Ford had wasn't enough. Once you get them tight enough you'll be good. I've read that a few times on here, not sure if it's true or not.

Thanks everyone, I will check the plugs as soon as I get the opportunity...

They can back themselves out if they are not torqued down. Torque to 28 ft lbs and it should never be an issue.

28 wasn't enough for mine. I had to go up to 35.

Take a look at fuel rail and injectors .
Do you think someone could have moved fuel rail and not bolted it back down . How about o-ring leak on injectors . Possible leak on fuel rail pressure sensor .
Fuel filter leak under drivers side of truck ?
Torque those sparkplugs in for sure . Don't trust you gut feeling on tight . Use rubber spark plug socket . Always start plugs by hand and good feel . Back it out if it doesn't go easy . Drip some carb cleaner in there to soften carbon that wants to seize tip and maybe stop it from lining up right on threads ,let it evaporate before putting sparkplug back in . Don't use power tools on spark plugs ,porcelain can't take it and alum threads are soft . Avoid side pressure on sparkplug when installing be very gentle putting these back in don't ask how I found that out .
Always blow out spark holes before removing plugs . Use nickle never seize on plug tips per ford tsb. I put a little on threads too . Copper stuff is bad for alum heads . I have big can from amazon lasts a long time .
.
Never have found a safe way to clean carbon out of hole with some kind of brush . Always feared it would break or get stuck . If I had a removed head to prove a method I would use it . I've looked at harbor freight stuff and gun brushes but haven't found anything I could trust .

Been busy working, I haven't been driving that truck so I haven't had time to check it either...
Will do tomorrow
