F-150 4.6L

  • Automatic transmission
  • 149,000 miles

This was the first time it happened and was quite the surprise. I had just left a job site when the spark plug spit out and it sounded like my exhaust pipe fell off but then I noticed it came from the engine and when I opened the hood, to my surprise I saw that a spark plug had come out from the engine head. WTF!!! So I called my mechanic and he fixed it later that day but told me it might happen again. SH*T!!!! And it did,, two more times later that same year. I need to buy a new truck. Ford or not.

This is not funny. It really is a pain in the ass. My work truck needs to get the job done and this really puts a wrench in my job.

i bought a 2000 ford f150 from ford dealership not had it for 48 hours when my plug blew. talk to head mechanic at ford he said this is typical on the 4.6 i think they should have to let the customer know these issues before buying and let customer decide if he or she want take a chance

F-150 XLT 5.4L

  • Automatic transmission
  • 134,000 miles

This is the second time this plug failed--the hardest to reach, right bank rear. The first time was at 95,000 miles when we changed the plugs. The plugs were torqued in place--I had heard about the issue, and made sure all were torqued. Within 6 months of new plugs, out it came. I was able to see the threads with a mirror and lights, and enough threads to replace. This was an extremely difficult repair! At 134,000, out it came again. This time I took it to a shop and had them drill and install the helicoil. They warned me that if it comes out again, the head will have to come off, at a several thousand dollar cost....

I am not pleased that this known design defect is not at least partially covered by a recall, or extended warranty, or a decent "fix" from ford. Do they think we will forget when it comes time to buy new??

F-150 XTL 5.4L

  • Automatic transmission
  • 133,000 miles


For 16 years my 2000 Ford F150, 5.4L V8, has ran like a champ. Regular maintenance, oil changes, the works. Today I repaired my sway bar links which come to find out is a common issue with Ford F150's. Drove it around the block and it rode smooth. I was ecstatic! I drive the 15 something miles home from my mechanics and as soon as I park into my lot, my truck sounds like it's back firing, like gun shots.

Some research later, I find it is the spark plug #3 and it has blown, which again, is another common issue with this vehicle. 16 years and this issue cannot be resolved!? This vehicle is my life. It takes me to work and home to make a living. The only thing keeping me afloat. This is not something that someone purchasing a vehicle should have to worry/think about years down the road as they are searching for the perfect vehicle.

As common as it sounds, it should be a recalled issue. An issue that Ford should take responsibility for and rectify, but now thousands or even millions of Ford owners have or are having to pay and repair for this issue and some even reduce their only resource to income because of an issue that should still not be occurring; especially 16 years in the making.

  • Automatic transmission

Not sure how you design an engine to work for so many years and not design it to keep from shooting the spark plugs right out of the engine. Never heard of this issue with any other vehicle except the Ford F150

F-150 Lariat 5.4L V8

it's pretty damn stupid if ford knows about this problem and they won't do anything about it. I called a Ford dealer and they told me it was 500.00 to fix just one hole, just think how much it would cost for all cylinders

F-150 XLT 5.4L

  • Automatic transmission
  • 172,500 miles


Was stopped at a light and when I pressed on the gas I blew out a spark plug on my 5.4L engine. Very loud popping noise and the cab of the truck filled with gas vapors. I was close to home but am very lucky there was no fire in the engine area.

Yes it's an older vehicle but spark plugs are supposed to stay put. In fact Ford is the only manufacturer that I have ever heard as having this problem.

It was rusty but trusty until now. It's been a decent truck but I'm not going to start chasing major repairs like head replacement. So off to the scrap yard with it.

The reason I decided to put this on here is that this is a problem from 1999 to 2004. How do you allow your vehicles to have such a problem in the first place?

F-150 Harley Edition 5.4L V8

  • Automatic transmission
  • 202,000 miles

Heard a ticking sound about a week before, but then it went away. 100 miles away on a Sunday night at 1am and bam, out came a plug. Drove it home. Got a cheap fix-it kit, must have dropped something into cylinder, started it up and bam, looked down, spark plug hole with scope and saw the end of the piston rod and wrist pin. (Piston exploded and also snapped valve off).. So off to junkyard and find crashed bad F150. Take motor out and work like mad to put it back together.

Many poor engineering problems 1. motor mount on passenger side will not allow enough clearance to accept exhuast manifold bolt to clear 2. converter will hardly push back to allow you to pull or realign motor to transmission 3. two upper bolts to tranny only accessible when you pull the intake manifold. 4. Have to drop exhaust pipe even to get starter out. I am not a smart mechanic but have changed more engines then I can remember and this was by far the most time consuming and troublesome I have ever came across.

Cripes, you can't tell me in this day and age something couldn't be engineered better then these plug spitting pieces of garbage. Come on mannnnnnnnnnnn!

F-150 4.6L V8

  • Automatic transmission

7am, started for work, blew as soon as I started truck. Removed plug from coil and could not replace in hole. Unhooked coil and drove to Ford garage to have it repaired, ran like a John Deer tractor on 7 cylinders.

Have had exhaust leak for several months but now I think it was the plug being loose all the time.

F-150 XLT 5.4L V8

  • Automatic transmission
  • 199,551 miles
  • While taking a turn and going back onto the accelerator pedal there was a sudden loud "explosion" like sound, immediately followed by a loud "vacuum leak" like sound. Sounded like the exhaust system suddenly came loose.
  • Pulled over, popped the hood and saw an electrical arch around the #8 cylinder Coil Pack. Turned off engine noticed Coil Pack was very loose and had broke from the mounting tab.
  • Upon further inspection the lower boot on the #8 Coil Pack was observed to be nearly completely shredded. The spark plug was still attached, but the external electrode had been completely bent over coming in contact with the center eletrode.
  • Repair involved retapping hole and inserting a Helicoil insert with hi-temp RTV silicon, with a new spark plug with anti-seize.
  • I had issues with 2 Coil Packs "gone bad" between 80 and 96k miles. Orignal set of plugs changed @ 96k miles. Then again with a third Coil Pack around 110 - 115k miles. Had remaining 5 Coil Packs replaced as a preventative measure.
  • As far as I know there was no issue with blown plugs at any time of the Coil Pack replacements. Therefore this was my first (hopefully last) blown plug.
  • Perhaps that makes me more fortunate than others, since this occured at 199,551 miles.

F-150 Lightning 5.4L

  • Automatic transmission
  • 100,650 miles

Ford doesnt issue a recall for this problem,I just now had this problem with my 2000 f150,it has a 5.4L with a supercharger,it a lightning,but it doesnt matter how its set up it does it on any 5.4L. If you want to read something from outside, read popular mechanics(Nov 2010,Pg 117). when it happend to me I was just starting my pickup,when I shut it off just before that it was fine and I don``t abuse my truck. I bought the truck In 2003 and I never heard anything about this problem at the time but it said in the report that it was not covered in the warranty but because ford cause this problem when they built the 5.4L I think even now they should cover it or most of it, If it was a normal problem I wouldnt say much about it
