2002 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 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.
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.

2002 Ford Expedition Reviews
Replaced serpentine belt then alternator . Now the shift cable has broken or something . All this has happened this month. I hope when we fix this it will go for a while & not cost me money for a month or two. When its not broke its a good truck
I bought a 2001 with 6 miles on it ( she now has 149000! ), and have been 90% thrilled and 10% pissed. Everything with this SUV is fine, great even- except for really one thing: paint issues. The fiberglass hood is corroding, which is weird, and Ford knows about the problem but wont fix it, even under warranty. So Im not happy with those prcks for that, but otherwise she is a great truck! I will run her till she drops, and may get another one, if I gt past there poor customer response.
best car I ever had
