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
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
Previously I owned a 2001 Harley Edition and experienced no problems. I updated by purchasing the 2006 Harley Edition and couldn't be happier. This truck rules the road. There are more amenities in this truck than in some luxury cars. If you are looking for a truck that will turn heads, this is the one!
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.
