Anonymous, IL (2006 Ford F-150 XLT 5.4-L V8)"There is a known defect with the spark plugs in the 5.4L engine with a large service bulletin published on how to remove plugs without them breaking apart. It costs about $100/plug to change and can require specialty tools to remove broken plugs. 100K mile plugs are now recommended to be changed at about 60K miles to avoid breakage. Two coils went out at 65K miles and second complete plug change at 120K miles"

Anonymous, AR (2006 Ford F-150 XLT 5.4-L V8)"This was a problem that started and lasted for a period of 2 months. Definitely you felt the engine was running rough and missing. Due to the specialized spark plugs kind and system Ford uses, it was difficult to completely diagnose and fix. After a few attempts to solve the problem by replacing the "problem one" spark plug(s) and wires, the problem continued. The final solution was to replace ALL the spark plugs and wires at once, including the ones individually replaced before. This was the solution. Afterwards, the engine run great and steady."
Anonymous, CA (2006 Ford F-150 Lariat 5.4-L V8)"Starter located in an area that is very difficult to access. Best advice for diy? Drink 3 or 4 beers and call a mechanic before attempting to remove and replace. Design engineer must?ve had a mean streak!"
