Here's my update.
I'm the "Dan" guy who posts about 3rd Ford truck and still impressed.
I finally started to get a misfire.
Dealership said it didn't throw ONE SINGLE CODE (like all other keep posting about) no cam phasers, sensors, lifters etc.
Replaced all 8 plugs, and misfire is resolved as of yesterday.
NOT ONE BROKE!, only 56k, but still 6 years old.
I really think the 2 piece spark plug design is horrible and YES causing a lot of you financial hardship, however....change them at or before 60k.
I really think that any V-8 not changing plugs til 120k, like I keep reading will obviously give someone a lot of trouble removing.
Use Mobil-1 5w-20w, NOT the old fashioned sludge 10w-40
If you are thinking about buying an 06 F-150, I highly recommend going to any auto shop and asking how much it will be for a tune up. The problem is the spark plugs break off when tried to be removed. So did Ford do a recall? Nope. They made a special tool that shops have to buy to help decrease the chances of breakage. BS!!!
Does the tool work? Sometimes yes, sometimes no. Half of mine broke even after they were soaked overnight.
My bill? $1000!!! Very disappointed in Ford.
Ford continues to have a "Better Idea". It doesn't have the best engine, it doesn't have the most impressive interior or exterior, but in the final analysis, it is the sales leader year in and year out because of the package. The whole is greater than the sum of its parts and that is the key. It offers an excellent combination of comfort, power and styling that aces its competition. My XLT Crew Cab with Texas and Oklahoma Package came with power seat, mp3, 6 disc CD, running boards, 4.6L V8, automatic, keyless entry, 3 interior power points, enough room for six adults and it can tow a small yacht with ease. It's about the package. It is not the best at anything specific, but best overall.
I read he horror stories, and I still what's going on.
3rd Ford truck and still impressed.
2 Rangers, now a 5.4 XLT Supercab 2006.
No plug blow outs, no leaks, oil lifters etc.
I do, however, after research and experience, think the 5.4 is a high maintenance engine.
MUST use a light weight FULLY synthetic oil, K&N air filter, the correct oil filter, and CHANGE PLUGS at 60K.
Run fuel injector cleaner every 3 fills.
I only have 46K, but I really think preventative maint. is the key.
Are some of you "romping" on these trucks? ie; break-stands, tug-o war?.
Who knows, I may have all these problems at some point but I have never had one single malfunction/problem with ANY of the 3 I'v own
