Part one of Diagnosing spark plug foul. I changed the plugs out and still have an intermittent miss while cruising at low RPM when I hit the gas. Si here I am trying to fix the problem and giving some helpful hints along the way.
No code misfire
So you have a car with a clear misfire but there are no codes. Don't
worry, you can still use your scanner & labscope to quickly and accurately
identify the problem and fix it with confidence without throwing parts at
Replace Spark Plugs 2003 Ford Expedition
How you can change spark plugs in a 5.4 Windsor in a Ford Expedition. It
took me about eight hours over two days. My engine was misfiring badly.
This fixed the problem. I am slow and methodical.
Gotta add that talking to myself in my garage is sort of weird. Sorry for
the lame narration.
Replacing blown out spark plug
A common problem with Ford Triton engines is that they will blow the spark
plug out, usually # 3 or # 4 on the passenger side. Some people say the
only repair is to take the head off. There is a tool designed to drill
out, re-tap, & install an insert. I've done it many times and so far they
all are still holding. I thought you might like to see how it's done
before you do one yourself.
Changing Spark Plug on 01 Ford Expedition - # 5 Spark Plug
This is the beginning of a series of videos I will be uploading over the
next few weeks of regular routine maintenance of the Ford Expedition 2001.
I will be hopefully adding a whole lists of projects to be done, and will
video the work as it is done. If there is something you would like to be
seen done, send me a message, and I will see what I can do.
How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.

this article I wrote.

Ford Explorer spark plug fix
Ford blown spark plug repair - Time Sert review
Vehicle: 02 Ford Explorer V8 4.6L
Many Ford engines from 1997 to 2008 with Triton heads may blow out a spark
plug. Many companies have come out with a relatively inexpensive fix that
allows the Head to remain on the engine, thus saving a lot of money in
repairs. Although I have rebuilt engines in the past, I have never
repaired this kind of damage to an engine. I wanted to record whether Time
Sert's claims were as easy as they proclaimed. The answer for me was
The only criticism was that I had no objective idea how much counterboring
I needed to do. With the engine that I had, a Lot of counterboring needed
to be done and I thought I had gone too far at one point simply due to the
amount of time spent with this operation. I have done a second repair and
decided to only use a hand ratchet on the counterbore. It took two hours
to counterbore alone. I recommend an air ratchet for this reason.
Bottom line is that this works; It's relatively inexpensive; and I was
overall happy with the product. As well, I can now replace more threads
without buying anything more since it came with 5 inserts.
