While driving 45mph on suburban two lane highway i heard a loud bang and subsequent rhythmic popping sound accompanied by an engine misfiring. Upon inspection i found the # 4 cylinder spark plug lying on the valve cover; un attached to the cylinder head. The mechanic found the threads "blown out" of the head and had to utilize a heli-coil kit to repair. The spark plug was a motorcraft original equipment part. This…

Spark plug blowout on 1999 ford f150 with 5.4l triton v8. It seems to be a very common problem with the ford modular engines. Today, i heard a loud pop come from my engine bay as i accelerated and then the sound of what seemed to be a massive exhaust manifold leak. Upon further inspection, i found that the spark plug on the rear passenger side of the engine had ejected and broke the coil with it. I was lucky that it…

On four separate occasions, the vehicle began idling and accelerating roughly for about 2 days. The check engine light would come on after about a day. The problem would stop and the light would go out before i had the chance to take it to a shop. This last time, march 27, 2009 it had been raining for a day or two. I went to start the truck and the engine was idling and accelerating roughly again. Upon taking it to…

Went outside to start my truck 1999 ford f-150 5.4l. As soon as i started the truck i heard a loud banging, shut the truck off, open the hood, and a spark plug had blown out the head ripping all the threads out and breaking the coil. So now my $14000 truck is useless. My only options include $3000 for new heads or a heli coil kit which will eventually allow the same problem or worse to occur. *tr

I purchased my '99 ford f-150 in the spring of '04. At the time of purchase the truck had just over 49,000 miles on it. This past monday (10/16/06) while pulling out of a local parking lot, the #2 spark plug was ejected out of the right cylinder head, ripping out the threads that the spark plug screws into & destroying the coil pack located directly above. My truck on the day of failure had 81,790 miles on it.…

When i started my vehicle their was a loud popping noise, further investigation showed the #2 cylinder coil was jumping up and down. When i pulled the coil out the spark plug came with it. The aluminum engine head had stripped out the threads that hold the spark plug. Further dealing w/ ford dealership, as to how to fix the problem, is to replace the head at a cost of 2500.00 plus. *nm

The truck would barely run and required a tow, the dealer ship said that the spark plug had ejected from the engine due to stripped threads in the block.

Dt: on september 23, 2005 had a spark plug blow out of the cylinder head of the vehicle. This was the spark plug on passenger's side, nearest to firewall. This was the third coil that the consumer had, but this it was the first time the spark plug came out. Contacted the dealer, they towed it. There was no forewarning. At 65 mph, the consumer heard a pop and thought it was the tire, but it kept popping until vehicle…

What actually happened was my #3 cylinder spark plug blew out. Thankfully it did not cause an accident. After investigating how to fix the problem i learned this was becoming very common with ford triton motors and would…

I am shocked to discover the thousands of postings on the internet concerning the '99 ford f-150 that blows a spark plug because of too few threads on the engine in the original design. As a victim of this failure, the dealership acknowledges that this happens all the time and that there is no remedy for it. The cost for repair is almost $3000 and there is no guarantee that it will not recur. Seems that ford should…
