1998 Ford Expedition Problems
There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.
An illuminated Check Engine Light could indicate that one or more of the ignition coils has failed due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.
The mass air flow sensor (MAF) may fail resulting in a rough engine idle, hesitation on acceleration, and/or engine stalling. The Check Engine Light may or may not illuminate. A failed mass air flow sensor will require replacement.

I purchased a 98 Eddie Bauer with 198K miles in April 2011 for $4400 cash. It is now May 2012 and I have 251,100K miles on it. I put 53k miles on it within one year. I just recently had to replace brake pads and have the rotors turned. The air conditioner doesn't get as cold but for what I purchased the vehicle for I have a darn good truck truck!
