I have a '99 f-150 XLT 5.4 triton.I am hoping this is as easy as you make it sound.I am a woman and know very little about cars, but after waiting for 2 years for some male to change the plug on my truck I am going to attempt it myself. My problem with following these directions are that, when you are naming the parts to be removed, I don't know what they are. Tomorrow during the day I will be taking my laptop out and have this page by my side to assist me in this. Wish me luck! Although its been 2 years, the truck hasn't been driven the majority of that time, and been parked and covered, so although I know that it would be best to change all the plugs at this time, I really just need to change this one because it is misfiring. And then I can at least use this truck.
