I need a diagram for a 2002 Ford Expedition for spark plugs

There are kits for stripped out spark plug
threads in the cylinder heads

Google the issue, lots to read

if it's a four cyl engine then it's the first plug on the passenger side of the car.

Spark plugs and wires,
Bad or leaky vacuum line
Bad 02 sensors, (check engine light would likely be on)

If it doesn't do it at idle, then motors mounts should be good and the problem is one of the listed above.

Check this diagram for 2003 Ford Expedition 4WD 5.4 liter SOHC V-8 VIN "L"...



Hope helps (remember rated this help).

Check this for 4.6 or 5.4 sizes engine...

2004 Ford Expedition 4.6 liter V-8 VIN "W"




2004 Ford Expedition 5.4 liter SOHC V-8 VIN "L"



Hope this help (remember comment and rated this).

they have free tech solutions and diagrams...........

Plugs are near the top of the cylinder heads facing upwards. They are not fun to change as the passenger's side doesn't have a lot of room to work in.

no special tools,this is what tools you will need:.7mm socket for the coil packs where underneath them is a deep hole and down there is the plugs---8mm socket for the fuel rail bolts(for the left side sitting in it)which i would use 1/4 inch drive for these--- 5/8 plug socket---6 inch extension---3 inch extension---ratchet---swivel---which i would use 3/8 inch drive for these---and maybe long needle-nose pliers incase the rubber boot from the coil packs come off and sticks to the plug.

The 4.6 L SOHC engine used in the 1997 F-150 has a spark plug firing order 1 - 3 - 7 - 2 - 6 - 5 - 4 - 8
