1999 Ford Expedition ProblemsTSB 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.
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.

I closed it one day tried to open it a few days later and it would not open at all. Not even with the key. Or with the witch on the driver's
door. I called the Ford dealership here in Hattiesburg and they wanted $90.00 just to look at it.
