98 F-150 plugs
Ive read about the horror stories on this forum about changing the plugs out on the 5.4s, but havent heard anything on the 4.6 engines.
I like to do most of the maintenance myself, but is this a job I really want to take on?
I have a 1998, and a friend that owns a 97 just did his, and said he would never do it again.
Im a little more mechanically inclined than he is though, but now Im a little more hesitant in attempting this.
Any advice, or opinions?

Well the 4.6L isn't quite as tall so you'd have a little more room to work with. I've only done a 4.6L in a Grand Marquis and it was incredibly easy, but the trucks have the engines shoved half way under the firewall where as the cars don't. I won't do my 5.4L it just isn't worth my time to aggravate me that much, I tried once and have it done from then on.

I used a rubber filled socket to get them out and a length of fuel line to start the new ones and then a regular socket to run them in. Try blowing the holes out with air before you begin. Use anti sieze on the threads and dielectric grease on the boots.
I loosend but didn't remove the tall verticle PS reservoir bracket and removed the reservoir to gain a lil more room. I also unclipped the injector around where I was working so I didn't thrash it by accident. The back passenger side is the most difficult. Start with that one so each one will get easier. Oh. USE MOTORCRAFT PLUGS and MOTORCRAFT wires.
