2003 Ford Expedition ProblemsRough 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.
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.
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.
