1999 ford f-150 with a 5.4l triton v8 engine... Problem: blown spark plug after work, while accelerating onto the freeway, the engine made a "pop" noise, and then began to sound like a steam engine. The engine was running rough and loud, thus i pulled over on the side of the road. I was concerned that i may have blown a spark plug (or possibly a valve) and didn't want to set the engine on fire. I was stranded until…

Sitting at stop light in 1999 f-150 w/5.4 litre engine,slowly proceeded through light and heard a loud bang followed by very loud and rough running engine. This left me stranded at side of road at 3:00am. Turns out that spark plug ripped away from cylinder head causing expensive repairs. This not only is an obvious mfgr. Defect,but a safety concern as well. The manufacturer knows this is a problem and should step up…

Was driving the truck home, about a mile out after being on the highway, there was a loud bang. The spark plug had been shot out of it's place, per a shop owner. Not sure why it happened yet. It was stated to us that ford has many complaints of this happening to their trucks. We have a 99 f150 and wondering if there are more such complaints and if so what can we do to push the issue. It could get someone hurt at…

Slight tapping that of like a tapping valve for about a week prior to first incident. The second incident occurred with no warning that i noticed.*ak vehicle has now ejected two spark plugs. Spark plugs were not the original from the factory. The first one was on the passenger side, 3rd back. When it came out, it destroyed the coil over the plug as well. It was repaired using a heli-coil solid steel insert which…

The number 3 spark plug blew out of my 1999 f150 while pulling away from a stop light. The aluminum head has only 4 threads holding the plug in place, clearly a design defect. I had both heads removed and had all eight holes repaired...total cost was about $3,000. There was 80,000 miles on the truck at the time. Ford should stand behind their product! *tr

I take good care of my pickup however it has broken down on me. It began with a small shutter. It felt like the pickup was having issues idling/accelerating. Only at low (5-10 mph) speeds did i feel the weakness/shutter. I had this issue for about 4 months, i just assumed it needed a tune up and was prepared to have one done soon. I was towing a trailer (started off fine) then at a stop sign felt that the engine was…

I was towing my trailer and had just left my house and got a mile down the road when i heard a loud pop like a tire blowing and i quickly tried to find a place to pull over. I later found out i had a blown plug and of course it wiped the threads and shot up and destroyed my coil on top so i had a helixcoil put in and a new coil . My truck is a 99 5.4 with 67,305 miles on it with the original factory plugs . *jb

My f150 p.u. Has a stress crack in the curve of the door by the window. The latch is not tight enough, so the door is hard to shut. My windshield wipers turn on by themselves, the odometer light goes on & off, the seat belts do not recoil & the "door ajar" light gets stuck, eventhough all doors are reshut. Engine sometimes runs rough eventhough has just had 60,000 mile check. The ford dealership wants to charge me…

While driving at 65 mph, suddenly there was a popping noise, then the vehicle stalled. The spark plug had came out the engine cylinder head. This occurred because of a design flaw, there was insufficient tread to hold the spark plugs. The cylinder head was replaced. *jb

The consumer took vehicle for service because of a ticking noise heard on vehicle. The dealership indicated that the ticking noise was coming from the catalytic converter, and the head gasket had blown. Which resulted in an oil leak into the exhaust manifold. The dealership replaced the catalytic converter and the head gasket; however, the ticking noise still exist after the repair was performed. Within 300 miles…

Have a 1999 ford f-150 with a 5.4 liter engine. #3 spark plug blew out and had to have a costly repair done by the mechanic pulling the head and placing an insert into the hole. Killed 2 birds with 1 stone because the passenger side head was leaking oil. This same spark plug had blown out two previous times. Finally decided that something was wrong. Have driven fords all of my life. Not sure will purchase again.*ak

1999 ford f150 blown head gasket right side can't afford to pay 4700.00 dollars to replace gasket & head. Ford knows they have a problem with the gasgets on the triton motros but fail to take blame. This is a fire hazard when oil is leaking on the exhaust. Recall!! Before someone gets hurt or killed. *jb

I never abused my 99 ford lightning in any way and @ 21000 miles it blew #3 spark plug out of the head. Ford finally agreed that if i would pay $817.00 for the deductible they would pay the rest. I don't think i should have had to pay anything since the head was defective from the factory. *jb

Also at an earlier date the sheet metal on the drivers side door about three inches from the bottom of the window cracked. Its has cracked two more times since then.

*aki was driving my 1999 ford f-150 with 5.4 liter v-8 engine when i experienced a blown #3 spark plug driving under normal conditions on my way to a soccer game. Extended warranty company would not cover problem. Got it fixed with a helicoil for $400 and same #3 plug blew 4 months later. Got it fixed with a new head unit for $2500. Now i want ford to reimburse me for flawed engine design.
