2003 Ford Expedition Problems

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.

Check Engine Light due to worn spark plugs

An illuminated Check Engine Light may indicate that the spark plugs are worn; this will cause intermittent misfire and damage to the coil packs.

One or More Spark Plugs May be Ejectioned From the 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.

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.
