1999 Ford Expedition ProblemsOne 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.
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.
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.
