Hello,

I am new, just signed on.

My truck, a 2000 Expedition. Spark Plug #5 is mis-firing. I found this out
through a free diagnostic at the local auto parts store.

Are there any tips on how to replace a spark plug, I am a single mom, in a
new city, with no money for a dealership.

So if there is any way this can be done at home, I follow good directions
really well, and if anyone is willing to help.

It would be greatly appreciated.

Thanks so much in return.

Michelle

Changing a spark plug is pretty easy, but you need some tools to do it.
There is a special socket used to remove sparkplugs, essentially just a deep
socket 5/8" or 13/16" socket, and usually has a little rubber grommet inside
it to keep the sparkplug in place while you are trying to get it threaded in.

If you have this tool, then I would replace all of the sparkplugs. Buy them
from the local autoparts store you went to, and make sure you ask them if
they are pre-gapped. (very important).

Once you have them, its a simple matter of removing the old plugs, and
putting the new ones in. Be sure not to cross thread them, as this could end
up being an expensive fix for you. When you are tightening down the new ones,
make sure to only turn them 1/2 a turn from when they become snug.

If you don't feel confident, then I would definitely take it to a shop, or
ask someone who knows. Its pretty easy to bugger this job up if you don't
know what your doing.

There can be more to it than the plug itself. You have a misfire on the
#5 cylinder. The plug wire may be bad. Or the injector at that cylinder
might be bad. The plug is the cheapest thing to change so in your
situation it's well worth a try. Maintenance is never bad.

Unfortuntely changing the plugs on an Expedition can be difficult. The
later model Expedition engines all use individual coils on each plug
(earlier 4.6L engines used a setup with four coils and traditional
wores). Lucky for you, the #5 plug is the front left plug (front plug
on drivers side), so it is relatively easy to access. The Ford
procedures call for removing the fuel rail that is located over the
coil packs that are installed on the plugs, but if you are only
changing the #5 plug, this might not be necessary. It is not
necessarily the plug that is bad. In fact it is more likely that it is
the actual coil, or the coil boot. For a description of the proceedure
for changing the plugs, see:

http://truckworld.tenmagazines.com/t...42&cat=12&sc=2

Be sure to torque the new plug properly. At a minimum I'd replace the
plug and boot. These two item are relatively inexpensive. The coil will
be around $70, so you might want to chance not replacing it. This is
not an easy job for an inexperienced mechanic. Be sure the engine is
cool before you start. Otherwise you might strip the threads in the
head. Also be very careful when you install the new plug. If you cross
thread the plug, you will have major problems. And be sure to torque it
properly - use a torque wrench.

I also recommend you join the Expedition Owner's Mailing List and ask
that group for advice. See

Take it to a car wash and give it a good cleaning,
especially around where you will be working.
Anything that falls into the plug hole will go through
your engine as soon as you start it.

Also each cylinder has it’s own coil,could be the coil or the boot
that connects the coil to the plug.

I have replaced more coils than I have plugs on this type of Ford
SUV.But like someone has already said the plug is the cheapest thing
to try first.
