2003 Ford Expedition Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 Ford Expedition

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.

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.

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.

We got our 2003 Expedition from a friend with 204,000 miles on it last December; as a 3rd car for guests to use at our B&B. So far, it's worked well - I'm changing out the spark plugs this week (100,000 miles + on the old ones) and keeping an eye out for problems, but so far it's been a great "carriage" for us.
