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.
Ford 4.6L 3v spark plug removal - tips for success to address a misfire issue
Did this after searching everywhere and find nothing but negatives about
doing this. (except for the Mustang guy with the tattoo on his
arm, his video was helpful too)
I had random misfires and after changing the easy part (coil on plugs) it
still happened occasionally. Bucking and skipping like I was on a rough
road. My plugs were original (Dad bought truck new and never had them
done) and it has 104k on the odometer.
I can TOTALLY see how it can be a nightmare, but here is what I did with
100% success on a 2008 Ford Explorer v8 (4.6l 3v) - as a side note, the HTI
plugs at autozone were 11.99 each but they have a rebate where you get $20
back for 4, and they let you buy and rebate twice. Pretty cool to get $40
Take your time and dont rush it, slow and steady, on a warm motor with LOTS
of PB spray worked for me. Crank motor with all plugs out to blow out as
much PB as possible then change the oil when done.
Here is a follow up video with some parts that really made the truck wake
up and scoot!
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.

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.
