misfire, me too!!! P0301
But I hope I got mine fixed. New coil and spark plug swap out. 179,000 on my truck, plugs were last done at the 100K mark.
new vs old plug
What does the old spark plug look like to the wise men here?
i plan on doing all the plugs when the weather gets a bit nicer here, hopefully soon. I just wanted to get this one done, luckily the easiest to get at for practice.
Thanks.

Motorcraft plugs are nickel plated, they don't need it. Using it can give you false torque readings.

Q: Why do you prefer 28 foot lbs torque instead of the factory specification?
A: Over the past few years we have heard from many of our customers that they tightened their plugs to the correct torque but they still came loose. We worked with 10 other Ford Certified Master Mechanics and concluded that 28 foot lbs of torque would be satisfactory. We have been using 28 foot lbs of torque for many years and have never had one come loose or strip out. To verify that we would not damage the original threads we used a test cylinder head with good factory threads we applied over 100 foot lbs of torque to the spark plug without any failure.
Q: Do you use Anti-Seize when you install new spark plugs?
A: No, we always use Motorcraft nickel plated spark plugs to stop any issues with electrolysis.
