I've had two plugs blow out on my 99 f150. It has less than 100,000 on it. If they know its a defect why not step up and fix the problem? It cost $300 a plug!!!! Left me stranded at night with my family along the road!! Makes me wonder if I want to stay with ford or go elsewhere.

I had just got off work and was leaving the parking area and blew out the number 4 sparkplug on the right side head. I shut off the my truck and parked it. I called a friend that lives close for a ride home. The next morning I drove back to the plant and took my truck to the local ford dealership. They said that I should replace the head or install a helicoil and also replace the spark plug and coil pack. So I had them install the helicoil and replace the damaged parts. Less then a month later I was driving to work on the I 90 and I blow out the number 5 cylinder spark plug and this time it took out the plastic shield and ripped the spark plug and the coil pack off he truck. I have not done any thing but contact ford motor company about this at this time. There suggestion was to replace the heads my self at a cost of 6,000 dollars.

I was driving my 1999 ford f150 4x4 with 5.4l engine home from work and stopped at traffic light. The light turned green and I proceeded to go and then "pow" the truck began to make a loud "popping" noise and lost all engine power. I was in the middle of the intersection and somehow managed to keep it running long enough to get through the intersection and on a side road. I hesitated to open the hood because of the strong gasoline smell but it wasn't on fire "yet" so I opened it and found one of my ignition coils (coil packs) loose on top of the intake manifold. Upon further inspection I realized the spark plug had blown out of the aluminum cylinder head. I was able to catch a ride to the auto parts store with coil and plug in hand. The salesman at the store immediately knew what had happened and even knew the engine was a 5.4l before being told. He said that if I was lucky I would probably just have to install a helicoil or threaded insert in it. The other option was to replace the cylinder head. I purchased new coil and plug then drove back to my truck. I tried to clean the threads with a spark plug thread chaser but there were no threads left to clean. I searched the web and found numerous complaints of the same issue. Some people said they had multiple spark plugs blow out or "spit out" on the same vehicle. Why doesn't ford have a recall on this? The gasoline smell was due to the fuel injector still spraying while the plug was blown out of the head. What if it had caught on fire? I haven't repaired it yet but will try the "repair kit" that was handed to me when I bought the coil and plug. I think ford should recall all the 5.4l engines that have this problem and install the helicoil or insert to prevent a customer breakdown or a potential vehicle fire.
