Ford recommends changing the spark plugs on my 2004 F150 5.4 3-valve at 100,000 miles. Mileage was getting close so I tried to change them. Unfortunately Ford did not tell owners that there is a huge problem with the spark plugs breaking-off in the cylinder causing a massive repair bill. Engine had must be removed to take out broken plug. Ford did produce a tsb, but did not inform owners that this routine service should be done by dealer. Upon checking internet, there are scores of reports of the plugs breaking when both owners and dealers attempt the routine maintenance.

Without any warning the V-8 5.4 engine started missing, dealer in winslow AZ said they had a lot oftrouble with that engine shooting the spark plugs out. Two of the plugs were loose, one apparently more than the other. Replacing plugs did not help. Some reports of others tell of this going on since before 97. Some with fires. I wonder why this situation has gone on so long and still not fixed.

I purchased a new 2004 F-150 VIN [xxx] in Aug 2004. The safety issue I have is that we began having a problem with the vehicle stalling while it was being driven and for some reason when the vehicle was turning left. It was not a constant thing when we were driving the truck. However after a few occasions over a couple months we took it to the dealer.we took in on Feb.1 2005. The vehicle had 2600 miles on it at this time.the dealer concurred with the problem and the dealer contacted Ford Motor Company for assistance on how to correct the problem.the dealer did as they were instructed by Ford and did checks and inspections of several systems. They thought they had it resolved.but a month to six weeks later it began stalling again.only a couple of times at low speed.then some time pasted it did it again then a week later it shuttered while entering traffic. Then 3 days later it stalled in the middle of a three lane expressway blocking traffic for more than an hour.in the past everytime it stalled it would restart. This time it would not crank over but it had a hot battery.it was towed to the dealer they diagnosed it as a bad mircoprocessor I believe. This was replaced, it did not cure the problem.the current mileage on the vehicle is 4700 miles. My safety concern is that as many times as this vehicle has stalled I have not been hit by another vehicle. But my luck may run out. Have others had similar problems, have there been recalls in this problem or service bulletins. I emailed Ford and it was confirmed that they received my email but they did not respond for the second time.the dealer is very understanding buy if Ford has data that will help they need to convey it to the dealer.I need a resolution and an assurance that the problem is solved.its no different from driving a vehicle that the steering may break at any time.when it stalls I loses power brakes and power steering plus the danger of approaching traffic.

Truck continues to stall/engine dies when driving. Usually stops when slowing down or starting from a stop. Commonly dies at intersections/stop sings etc. Has stoped on highway when slowing down making it very difficult to control.
