Ignition coil in cylinder number 1 & 6 shorted out while washing the motor. Apparently these big block motors don't like water... (my fault)
The car weighs a little over 6,500 LBS, but the 5.4 motor pulls it hard, especially after 30 MPH.
Gas mileage is really bad, (11.3) compared to my Honda obviously, but I just love the Expo. It does so much more than the Honda, that it just makes it so much better to drive. With this I get safety, reliability & comfort.
Despite the car being 10 years old, the car has held up beautifully. Interior still looks new, even the wood trim and the A/C is ice cold. The exterior paint is a tad faded, being red, but it still shines.
I've owned many cars, From Nissan's, Honda's Toyota's, even Jeeps, but none of the cars I've had come close to how good this Expedition has been.
Despite the rumor of spark plugs flying out of the threads, I've never experienced it, on any of the Fords we've had from a 4.6 and another 5.4 we used to own.
I love the car and I highly recommend it to any one looking for an SUV.
All I need now is a scanner and spare coils, just in case.
Not a rumor about the Spark plugs flying out! My #7 plug blew. Fortunately, it was a relatively easy fix with a Hela-coil install, and only cost me a couple hundred. Much better than having to completely pull the head! I was still able to drive it, but it was NOISY (essentially down one cylinder, with exhaust into the engine area under the hood).
1999 Expedition XLT 5.4L.
Be careful not to over tighten the plugs when installing!! (I don't know if this was the issue, as I knew about it when I had the plugs installed at a dealer... blow out occurred 13 months later).
