Seven problems related to car stall have been reported for the 1998 Ford F-150. The most recently reported issues are listed below.
Incident #1 intermittent electrical contacts in engine bay affecting charging system, emissions, and drive systems. Ford dealer diagnosed as "bad alternator" and "bad wiring harness". After I brought it back without having repairs done, I cleaned and lubed all connectors. All problems went away. I ended up having to buy a new battery due to damage done by the faulty connections. The problems had been intermittent and progressively got worse before I cleaned and lubed all connectors, this problem cost me a battery, and almost caused me to wreck as the battery died at night on the highway. With no battery and no alternator, the vehicle stalled, lighting died, etc. Incident #2 leaking timing cover gasket and lower intake gaskets. At this moment the vehicle has 127k appx miles on it, and it is currently sitting as I will not drive it until it is repaired, all miles put on vehicle have been "light" miles (no heavy towing, no overloading of vehicle, no excessive speed, etc). Ford issued a bulletin stating that there was a problem with gaskets up until roughly 1/16/98. They then issued a customer satisfaction remedy that did not cover the full gasket set or all affected engine model years. According to the bulletin, my engine (mfg date prior to 9/97) is affected, according to their customer satisfaction remedy it is not eligible. In my book, this is something that needs to be the basis of a recall. Engines have died with as little as 50k miles on them, I have never had a vehicle that I was honestly scared to drive until now. I will most likely be performing my own repairs on this vehicle due to Ford's incompetence.
1998 F-150 5. 4l triton I've owned this truck for 2 yrs. And put 30,000 miles on it. Currently at 124,000. Other than maintenance (not including spark plugs) have changed both cv shafts and bearings in the front. Feb. 3, 08 without any warning or precursor it blew a spark plug from the head stripping the threads. It occurred very quickly while coasting down hill at 55 mph. Not hardly working the engine. I knew what it was immediately, I had been with a friend when his 2000 f 150 4. 6l blew a spark plug for the second time in 6 months. This action almost stalled my truck out being at low rpm to begin with it rattled violently. I was afraid my 10 yr old brother and I would have to walk for help. Not fun in NY in Feb. A passerby came to our aid. I had the truck towed home by a friend. Still trying to find a suitable and affordable repair. Thousands of these incidents have been reported to various websites, dealers, and even to Ford. Some instances have resulted in fires destroying the whole vehicle. Ignited by a stray spark plug and fuel mist from the cylinder. Something must be done by Ford. Most repairs run $2,000 - $4,000 each time a plug a spit. Many vehicles have under 100,000 miles.
While driving at any speed and without warning the vehicle would stall and it became difficult for the consumer to control the vehicle. .
While driving at 30 mph a spark plug (cylinder #2) blew out of cylinder head cracking coil pack. Dealer estimate for replacement of cylinder head is $3400. Vehicle is out of warranty period. This is a manufacturing defect that is very common in f150's particularly with the 5. 4 v8 engine. This is a stock engine, with factory installed spark plugs that are not required to be replaced until 100k miles. Plugs should not blow out of cylinder for no reason. This could cause serious injury due to projectile or risk of fire. Based on my investigation, Ford does not acknowledge problem. . Read more...
