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.

1998 Ford Expedition Problems
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.
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 may indicate that the spark plugs are worn; this will cause intermittent misfire and damage to the coil packs.
The PCV hose may crack, causing the vehicle to idle roughly, this may or may not illuminate the Check Engine Light.

RepairPal Expert Overview:
Ford has recalled 1997-1998 Expedition, F150, F250, and Lincoln Navigator vehicles due to a possible shift cable malfunction. On some vehicles, the cable may become detached from the steering column bracket. This may prevent the shifter from engaging the "Park" gear, even though it may still indicate "Park," and the vehicle could roll away. Dealers will secure the shift control cable to the steering column bracket and add a tie strap to the connection.

1998 Ford Expedition Reviews
I've owned mine for about 6 months now. 160K miles. Replaced front ball jnts, and battery. Just passed Missouri safety/emissions checks (2013), no problem. Runs like a beauty, ...I call her "Big Red!" I felt like I was getting ignored when I took it in for the work and safety checks, ...they had nothing to report on her! Told me to just keep rolling! I like it! I'll report back later. Only reason for any 4 stars, is that I haven't owned long enough yet!
my family bought our 1998 expedition new... through my older brothers abuse (for two years) and my abuse for the past three years, this vehicle is the best, it is about to click 200,000 miles and it has been jumped, slid around, on two wheels, went over a year at one point with no oil change, went for countless off road/mudding experiences, and still running strong. 5.4 is a great engine and has made me ford loyal! hope you have the same experience.
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!
1998 Eddie Bauer Expedition. 202,110.5 and still going strong. Only the air ride suspension just started leaking. I just bought the replacement air bags from strutmasters who really didn't want to sell them to me... tried hard to get me to go to their conversion kit; but I don't want coil springs. I like the air ride. It rides better and automatically levels the vehicle when loaded or pulling a trailer. I am on here trying to find help or instructions on installing my new air bags (air ride shocks).
222,XXX and yes still going strong.. having some issues with my heater, I am going to replace the heater control valve in the morning!
