Engine Exhaust System problems of the 2003 Ford Expedition

Spark plug ejection! I just experienced a problem with my Ford triton motor where the spark plug will eject from the aluminum cylinder head. I have a 2003 Ford Expedition that experienced this on Saturday. I was driving home from wal-mart with my family in the truck, we turned a corner and my heart stopped! it sounded like I was involved in machine gun fire. I pulled over immediately and my looked. Couldn't initially see anything. My husband checked under the truck thinking it was exhaust related. We were luckily 2 blocks from home, so we were able to get it home and into the driveway. My husband began trying to diagnose the problem and I took to the internet. He took the engine cover off and discovered the spark plug missing and the coil wire broken off and sparking. Long story short it seems that we have experienced the situation where the cylinder head has stripped on the one spark plug. We have begun looking into ways to fix the situation, but it seems Ford has not deemed this to be an issue. Truly don't understand how so many people can report the exact same happenings and no one will do anything about it. . . . . Merry stinkin christmas!!! we are reaching out to our local Ford dealer but am pretty sure they are going to tell us we are crap out of luck and will fall on us to repair if we choose.

I have a 2003 Expedition 5. 4l and since 2006 to present every two or three months I have to replace a coil pack and spark plug. Now since the coil packs have blown out so many times my catalytic converter on the passenger side has melted on the inside.

Spark plug blew out of engine head on a 2003 Ford Expedition with a 5. 4l engine the spark plug blew out of the engine head and gasoline were expelled on the engine and exhaust fumes into the passenger compartment. The engine head had to be repaired at a cost of $1,832. 48.

I was driving at about 15 miles an hour and all of a sudden I heard a loud pop. I had to have it towed to a Ford dealership. They said that from what I was describing it was a spark plug that blew out of the engine. But since it was almost 5:00 p. M. And they were about to close they wouldn't know anything until they could look at it the next day. I didn't damage the heads but it still cost me over $400. 00 to fix it.

I was driving my 2003 Ford Expedition to work this morning and heard a loud "pop" noise, the vehicle began to vibrate and I smelled gas fumes. When I lifted the hood, I immediately noticed that the engine had blown a spark plug.

The vehicle in question has been in the shop twice for misfire in the engine. The motor started running rough right after a startup one morning with a substantial amount of smoke coming out of the exhaust and about a week later another enormous amount of smoke on startup in the morning. The chain of events also caused other intermitten problems with the performance of the vehicle such as a sense of slack between the engine and rear differential when up shifting and down shifting. The vehicle also has intermitten problems starting , for example, you have to crank the engine three to four seconds longer than normal and at times I have had to stop the ignition and try again. There have been other problems with the vehicle that have been resolved and a continued problem with the mirrors moving when they are not supposed to, although I have not seen them move while driving as of thus far. Please note the incident date shown below is approximate and is when the problems started. I have filed complaints with Ford motor company,department of consumer affairs and mailed an application to the dispute settlement board offered through Ford motor company.
