You have what is called a 'coil-over plug' system, which means there is a seperate ignition coil for each plug. On each side you will see 4 small plastic boxes with a single bolt and some wires plugged into it. Remove the bolt, unplug the wires and pull the coil out. the plug is in the hole. Repeat for all 8.

I need to locate the number 4 spark plug wire to replace the spark plug can you tell me how to locate this wire on a 05 ford expedition


Your vehicle doesn't have spark plug wires . Has coil on plug ignition system . Eight individual coils sitting right on top of the spark plugs . An the spark plugs have the tendency to break in the cylinder head . Does your ford have the 5.4 L 3 valve engine . Your best bet is to take your vehicle to a qualified repair shop that has the tool to take the broken spark plug out off the cylinder head.

Where are the spark plugs located on a 1997 ford expedition 5.4l


The spark plugs are under 8 ignition coilpacks on top of the intake manifold. You have to lift the fuel rail on the drivers side to get the #4 plug out.

I cant find spark plugs


I am writing you the method on how to change sparkplugs, you may now have an idea where spark plug is loacted.

The Ford Expedition uses eight spark plugs to accommodateits eight-cylinder engine. Replacing the spark plugs every 75,000 miles is animportant part of overall vehicle maintenance. 1. Disconnectthe negative (black) battery cable from the battery terminal. Remove thewiring harnesses from the spark plug coils. There will be four on each side ofthe engine block, which you can remove by simply pulling them out of the sparkplug coils. 2. Unscrew the 7mm bolt from each of the spark plug coils usinga socket wrench and 7mm socket. 3. Pull each spark plug coil out of the engine block. Pull themout slowly, being careful not to damage or tear the coils. 4. Use a socket wrench and spark plug socket to unscrew eachspark plug from the engine block. Once you remove these, discard them. 5. Place the new spark plugs into the engine block and tightenthem using the socket wrench and spark plug socket. 6. Slide the spark plug coils back into the engine block. 7. Bolt the spark plug coils back into place using a socketwrench and 7mm socket. 8. Reattachthe wiring harnesses to the spark plug coils. 9 . Connect the negative battery cable to the negative batteryterminal.

Ignition Distributor location


There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps

2001 ford expedition spark plug location


That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing.  That's the fuel injectors.  BUT, right behind the yellow plugs, are black ones.  The black one is the connector to the spark plug.  The plug itself sits about 4 inches down into the block of the engine.  They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).
