I just joined this morning and have been reading random posts and it seems like the 04-08 f150's have a lot of the same issues.

I have an 06 f150 xlt 5.4. I bought the truck a year and a half ago with 15000 and now I have 46000. I change the oil on a regular basis (full synthetic) and I try to keep up on the PM. I will say this truck has not been very nice to me. I have had both rear brake lights, 3rd brake light and a fog light blow. I already had the truck in once for a ticking noise and according to the dealer it was just a vaccum line though it still ticks to this day. (If im in a drive through its pretty noticable like a desiel would sound.)

I previously owned a 99 f150 4.6 with almost 170000 on it and I swear I almost never had a problem. So I guess what Im looking for advice on is should I change my plugs and coils or could it be converter issues.... As a side note, the truck doesnt seem to have any more or less power since the day I bought it and the mpg is not that great maybe 15 at most. I want to put a lot into my truck this summer and hope you guys can help. Thank you for any imput any of you can give me.

that ticks probably cam phasers. makes our trucks sound like a diesel.

Well 15mpg is about average for the 5.4 but there are several after market products to help that.

I may be wrong but didn't the ford correct the cam phaser after 2005

Nope my truck rattles like a baby on speed with a rattle toy.

lol, mine seems worse at lower RPMs, does your truck rattle all the time?

Mine is idleing and when I am just taking off next to a drive up window at a bank where they have a canopy over head, then you can really hear it. Rattles like a diesel. plus I also have what sounds like a heat sheild loose so I get a tinny rattle sound on top of the cam phasers rattling.

I have that same issue. Before I took it in the first time it was really loud when I was towing a horse trailer uphill. My step dad recently bought a 2010 f150 and I noticed it seems to make the same noise when he takes off just not at loud.

Two things I did that greatly improved my gas milage was I bought an Edge tuner which I run on level 2 (towing) and I did this intake mod:
