Going to do my own tune up. I want to build a parts purchase list. This is what i have so far. My truck is about to roll 100k miles.

I know i need
Motorcraft plugs,
Brown cop boots.

I have no codes so i dont think i need the actual cops yet??

The not totally sure list.
Pcv valve
I want to clean the throttle body but im not sure how to get to it.

Am i forgetting anything important.?

This is my first expedition and want to do it right the first time.

That is a 2V. Similar but not the same. AFAIK all the 3V 5.4s are the same but either way this should be a lot closer....

And for the tune up plug, COP boots wouldn't hurt but I don't bother unless I have issues. Same for the COPs no misfires I wouldn't touch them.

The more I read the more I think changing the VCT valves may be worth the cost/effort. I'm beginning to think They wear over time and and contribute to phaser issues. But this is just a theory.
