This vehicle's sparkplugs are located on the intake, right beside the fuel injectors. This is a time consuming job, and it is recommended to replace all COPs (Coil on plugs) very costly!! **WARNING**>> Work on the plugs with the engine cold, these engines are know for very little sparkplug threading and causing the plugs to eject while in operation. Be very carfeful installing as they are installed at an angle.

I have a 2000 Ford Expedition with 157,000 miles. Do I need to be concerned about replacing the timing chain?


no you should not worry about changing timing. unless its not starting or something is really wrong that points you to the timing chain. i have 250,000 on my f150 never had no problems with timing chain. maybe a coil pack or sparkplug but no timing chain.

I HAD #3 SPARK PLUG BLOW OUT OF CYLINDER. HAD IT REPAIRED AND ALL NEW PLUGS, FUEL FILTERAND PCV PUT IN NOW TRUCK HAS A VERY FAINT ROUGH IDLE. ANY IDEAS


#3 sparkplug is not firing at peak performance.
The engine block sparkplug hole had to be re-threaded in order to accept an adapter for the replacement spark plug. The sparkplug is sitting "higher" in the cylinder than the others (not as efficient).
It may even be a different sparkplug altogether in order to accommodate the adapter.

Add a silicone insulator gel (AutoZone $2) inside both boot ends of the sparkplug wires and re-seat them all.
