After reading some of your reviews, comments and experiences with the coils, I also have a Ford truck with a Triton motor, either a 4.6 or 5.4 (1999-2003). From research and reading through web sites, I've learned that these two motors are built improperly by the manufacturer. Apparently the engine head was not properly threaded with fewer threads for the spark plug to screw into. Also, the robot on the assembly line possibly over torqued the spark plug, and most importantly, they did not use anti-seize on the threads of the plug. A few years of driving and carbon build up causes the plug to literally either blow out or undo itself from the head.
Customers that follow the service pamphlet are not at fault, because I believe the US service calls for the plugs to be replaced at 100,000 miles. But from doing a quick search on wwww.consumeraffairs.com, many complain about their plugs shooting out at 50,000 miles. Since it's a manufacturing defect, one would think Ford would cover the head at their cost because it's under warranty, but they claimed to have never heard of this issue, and exclude this repair from the warranty claim.
The only fix I've found is to check the plugs every 6 months or 15,000 miles, and to use anti-seize. But if you've suddenly hear a bang or your truck's driving funny, you might as well replace the head plus coil pack. There are repair kits, like Time Serts or a thread tapping kit that can be found online, but that's a temporary repair.

Going on my second coil for a 2000 Triton. Both failed after a hard cold rain. The first repair cost $300 for the coil replacement and $2,200 for replacing the catalytic converters that fouled from un-burnt fuel. 4 converters on this truck! Better idea my a#$.

I have a 97' expedition with the 5.4 l engine. I bought the truck in 05' and had to change the ignition coil #3 and air compressor ($600.00) at the dealer. We are know in 12/07 and the mechanic had to change #4 ignition coil and all the spark plugs $500.00. 50 miles later fuel gushed from the repaired area probably from the fuel injector. I'm bringing the truck back to the mechanic as he states there is a 90 day warranty on the repair. I hope he doesn't try to charge me anything for this dangerous error. Luckily I was not far from home with my toddler in tow. Among other things I needed repairs was the clips that hold the window to the regulator rack. I was told by the glass guy to replace the window as re-gluing the clips to the glass does not last long. this happened to to of my windows so far. Lastly I have this issue in cold weather where the power locks and courtesy lights turn on and off without explanation. Flush Our Reserve Dollars...

I have a 2000 Ford Expedition XLT and have had it since 2002 and I love my truck. I have had a problem with the gas mileage also, but I love my truck. I have also had to replace the rear airbags twice. Even though I had to do this, I love my truck. I started to look around for another vehicle since the gas prices just keep getting higher and higher. After looking, I am going to stay with my truck because I love the ride, the room, the towing... Just thought I would respond.

I love my 2000 Expedition 5.4 but... I have a shifting problem going on. When I take off from a stop it jerks like I am driving a stick shift, (mind you I am not very good at) when it is an automatic. My guess first would be transmission but this problem comes and goes. Had fluids changed and flushed. Has anyone else had this problem before? Taking it to a transmission place, where you know they will say it needs to be replaced.

Another thing to keep in mind is the fact that the front brakes are under sized for the weight of the vehicle. If you hear the rubbing sound you probably are going to be replacing rotors. I have to replace the brakes every year, my wife is a stay at home mom up in the hills. So maybe she is a little hard on it but, lets be reasonable 10-12k miles between brake jobs. If I could afford another similar sized vehicle, I'd let this one go right of the cliff!
Don't start me on the coil pack issues.

Hey, that is exactly how my expedition was acting, and they told me it was a coil. I thought it might have been my tranny, but it was intermittent. Found out it was the coil. There is a good chance that is what's wrong with yours.

I have a 2003 Expedition 5.4L (Triton motor). I bought it new. At about 90,000miles, the 3rd spark plug blew out. A month before that, the alternator died. Since I have had it, the passenger mirror would always reset itself when I unlock the doors. There has always been a leak at the driver handle (on the windshield) when it rains. I tried to get it fixed, with no results.
I also own a 2004 Ford F150 FX4 4x4; a nice truck but same bad engine. I bought it new; at about 24000 miles, the phaser cracked. Had it fixed, and exactly one year later it cracked again. Sold the truck to find out it also had a hole in the campshelf.
I also own a 1999 GT Mustang; I bought it new. Mass air sensor/ intake was always dirty and would stall the engine while driving.
I used to be a loyal Ford customer, but no more. I recently replaced all my cars with a Corvette, Lexus, and Toyota Tundra.

I have a 2000 Expedition Eddie Bauer with 21000 miles on it.
A spark plug blew out at about 100k. My mechanic retapped and that was it.
Drivers door locks me out when door is closed. Changed some switch at dealer to solve the problem. Still does the same thing (that's pretty annoying to have to unlock the door every time).
Gas mileage sucks.
Turn signals light but don't click when turning usually (haven't 100% ruled out fuses).
But guess what, that's been it. These posts are for people with problem cars, not the typical purchaser.
All I hear is that Ford engines are bulletproof, and my gut says they're infinitely more reliable than Chryslers, and at that point in time better than Chevys.
They're dated now though and kind of tacky, but the current models handle infinitely better.

Only good thing I have to say about this Expedition is I have 180,000 miles and it still runs strong, but the air ride suspension is a joke; it never seems to work right.
Just yesterday I pulled out of my drive and heard a horrible noise came from the rear end; well it was the whole axle trying to come out of the truck. The cheap traction bars rotted right off the axle, and with nothing else to hold it in place, the rear end ended underneath the back quarter; great idea Ford, lucky I was going slow, way to build them Ford...
