While driving at 35 MPH, a spark plug was ejected from my 2002 ford f-250 5.4l v8 pickup truck, causing the engine to stall and resulting in a loss of power for steering and braking. I'm told by my mechanic today, who identified the problem even before I told him why I was there, that this is due to a known defect with many ford engines, but that no recall was ever issued. Given the danger of fuel vapors escaping from the spark plug hole and risk of fire, perhaps the federal safety agency should press ford on the issue if it really is a common problem.

I experienced a leak in the power steering hose from the powersteering pump to the hydraboost on my 2002 ford f250 while driving in the mountains pulling a 30ft. 5th wheel trailer. I had to use 1 gallon of fluid to return 90 miles. According to another mechanic, this is a common failure and is due to poor design and engineering this hose is carried by the local dealer and they indicated that it has a high failure rate. This failure results in loss of powersteering and power brakes.

I own a 2002 ford f-250 w/ 5.4 triton v8. On this past sunday, while driving at 30 MPH, a large bang was heard form my engine. The engine began to lose power and slow. After being towed to my local ford dealer to be checked out, it was discovered that a spark plug had blown out of the cylinder head on the right side of the engine. The service manager at the ford garage stated it ruined the cylinder head and needs replacement. This service will require a large amount of work and new parts to complete. The cost will be $3400.00.

Any range of RPM while driving & occasionally while idling my truck has stalled and engine dies. It has, so far, restarted quickly and I continue on my way. This occurs in heavy to moderate traffic and when the truck dies you lose power steering & power brakes. I have been told to replace my cps (cam position sensor) by a ford mechanic and I intend to do that today. My truck is not safe to drive in it's current condition of random stalling.

Vehicle is a 2002 ford f-250 w/ 7.3l diesel engine. The cam position sensor (cps) failed. When it fails, the engine stalls. This means that a nearly 7400 pound vehicle suddenly has no power, including loss of power steering & brakes. The reported incident date is the date of the first failure (happened at a stop light). The second failure happened about 1 year later (while driving). When purchasing a replacement cps, the parts guy said they sell a lot of these (as in they fail often).

I have a 2002 ford f250 power stroke diesel truck. The diesel engine just shutdown as I was driving on a major road in memphis tn. I lost power steering and brakes but was able to avoid an accident because I muscled the steering wheel and the brakes to get my truck off the road into a parking lot. Fortunately I was in the outside lane and not traveling at 65 MPH or the accident could have been very serious. I am told that the problem is the cps although I just found that out today. The truck has been stalling intermittently at stop lights and sputtering on the interstate so I had a hard time diagnosing the problem.

I was driving down the highway at approx 65 MPH when all of a sudden I heard a pop and lost engine power. I pulled over and looked under the hood of the truck and observed a sparkplug lying in the engine compartment and the wireharness for it was torn loose. It was clear that a sparkplug had rotated loose causing it to come out of engine which caused sudden engine failure at highway speeds. The sparkplug which rotated loose, tore out the last 3 threads of the sparkplug hole in the cylinder head and destroyed the sparkplug wire harness. The truck was brought to the dealership on a flat bed truck. The cylinder head had to be removed and a helicoil put in to replaced the torn out thread for the failed sparkplug hole. All sparkplugs had to be replaced with new ones. A new sparkplug wireharness was installed. I observed that the ceramic portion of the sparkplug rotated independantly of the treaded part of the sparkplug body which would allow rotation of the sparkplug body independant of the ceramic portion. I do not have the sparkplug that rotated loose.

Truck (2002 ford f-250 powerstroke) engine randomly quits during braking or low/no acceleration. This causes loss of power brakes and steering. Braking and low acceleration occur in intersections frequently I have discovered. Truck will restart and problem may or may not return immediately. I took it to a dealership who said they could not duplicate the event and the codes set by the PCM were "unrelated". I took it to the dealer a total of three times for this problem. I read on the internet (www.dieselstop.com) that this symptom was frequently caused by a bad cps sensor. I went to an international engine (maker of the ford powerstroke) dealer and bought a new cps which resolved the problem. I have the old part for inspection if needed. This problem is dangerous. If pulling my trailer, loss of assisted brakes and steering could quickly become catastrophic.
