Recently purchased this 2003 Expedition with the 5.4L engine. Purchased on 12/20/2011. Since owning said vehicle I have had two spark plug failures. On cyl 8 and cyl 3. the first incident happened at a speed of about 25 mph. The second and recent happened driving highway speed, cruise set to 65 mph. The plug ejects from the cyl causing damage to the coil, and possibly creating a fire hazard. There was no recent tune up to my knowledge.

A month or so ago the truck started running rough and engine light came on. It turns out it was spark plug #4 misfiring. Replaced it and all was golden until yesterday (4/3/12) when I heard a loud pop upon starting the truck and then it was idling rough. Check engine light came back on and spark plug #4 is misfiring again. We bought this truck used and it's been one thing after another. So disappointed in Ford. Hope they address this issue and due the proper thing.

While driving at a low rate of speed, my Expedition made a loud pop and then strange knocking noise. Upon further inspection I noticed I had blown out a spark plug and my coil pack was blown apart as well. When I called a local Ford dealership (thomas Ford, stillwater ok) the man laughed and said "no it is not a recall, but absolutely should be as this is a very common occurrence in the Triton motor." I ask that you re-look back into this "common" problem as this is a terrible thing to overlook.

My wife was driving with our infant son and our teenage daughter in our 2003 Expedition XLT 4.6L 2X4. She heard a loud pop and the vehicle lost power and started smoking and shaking violently. She thought the Expedition was going to blow up. We had the Expedition checked out and the cylinder number 7 spark plug blew out. The aluminum threads in the head gave and the spark plug blew out, the injector kept spraying raw fuel and the coil ignited it. When all this happened it burned the ignition coil, coil boot, spark plug and the coil harness. Now we were told we would have to have the cylinder head replaced. We love our Expedition and I considered buying a new one, but I don't know now.

Expedition 8-cyl

After making a complete stop at a traffic light I made a left turn and began to accelerate when I heard a loud pop which at first I thought was a tire blow out. The engine was running so erratically that I could feel it in my steering. We inspected the vehicle for a flat when we noticed every tire was fine. I opened the hood and removed the top cover to the engine to discover a spark plug laying on top of the engine and the coil that was once attached blown off of the plug and damaged off to the side still connected to its electrical source. This cold have caused a fire. For the record these plugs were the original factory spark-plugs. Via the internet I have discovered this website to file a complaint.

Went out to warm up our Ford Expedition for work. Upon starting it heard a loud boom and the engine sounded loud. Had it towed to garage. Found out that the #7 spark plug blew out. For safety sake, Ford should admit to the defect in the engine, and issue a recall.
