2003 Ford Expedition Problems

TSB For Possible Ejection of Spark Plug From Cylinder Head

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.

Ignition Coil Failure Due to Excessive Spark Plug Gap

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.

Rough Idle Caused By EGR Sensor Sticking

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. Our technicians tell us the valve and sensor must be replaced together to correct this concern.

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.
