Bernie: Well the Ford, the interval from Ford is and I just looked this up is 144,000 kilometers is the normal service interval on spark plugs and a severe interval is 96,000 kilometers which gets me to talking about service intervals. The threads for the spark plug in that cylinder are now ruined as well as the coil for that plug. This is very common, perhaps inevitable on a 98T head. Luckily, this time, I was in a grocery store parking lot. The machine shop said head would have to be replaced, engine supposedly has to be pulled to get head off. While driving 10 mph, the contact noticed smoke entering into the vehicle from the front windshield.
As I turned left across traffic I heard a loud pop in my 2002 Ford f150 and then a loud series of loud pops as my engine continued to run. Found a simple solution - banging a wrench on it worked! Disconnect the battery, remove the spark plug cables, boots and spark plugs from the driver side, and put in the new spark plugs and replace everything. While it's a minor annoyance compared to transmission failure, ironically the crack usually goes right through the Ford logo. Ironically, the reverse problem is happening in the same engines where the in the engine. Once the fuel is ignited, it causes combustion, which in turn causes the pistons to rotate up and down and power the engine. Had to have it towed to a shop.
I was able to buy tools and perform a temporary repair in order to get my truck home. It is interesting that all the parts that were replaced were a different design than the originals. I have no idea why anyone would pull the tire off, remove a coolant tube or charge 3 hours labor to change the plugs in a 4. This is the first Ford I have owned in over 25 years and I promise it is my last. The truck started making noise and thought that it was the converter and a very short time after that first noise the engine froze and stopped running. Thought the back two on the passenger would be much more of a pain than they were.
The car started to run rough and gasoline fumes started to fill the passenger compartment. And also I forgot to put one of the wires back on the first time I started the car back up when I felt it running rough and then I stopped the car and put it on and it ran a little better but still puttering. It needs to be taken care of before someone gets killed, not after. I love this truck, it drives great, comfortable and for me not bad on gas at all. We were loaded down with 2 kids, a dog, and everything except the kitchen sink, towing a camper and the explorer just wouldn't start. It is serviced regularly and is used for routine driving.
Replaced all of the spark plugs and then, less than 3 months later, having issues with them again. My e-mail is wmickulas optimum. We believe this defect affects the following 2-valve engines: Triton 4. I will replace the engine somehow. When a plug is loose and an engine is rotating at 2000 rpm, it generates a tremendous amount of pressure each time it fires a cylinder. Ford doesn't want to stand behind their product and that is weak.
Bad or weak spark plugs can cause the engine to misfire and will lead to increased fuel consumption. While driving 65 mph on the highway, the spark plugs stripped out of the engine block. . If not by recall, it is obviously a factory defect and should be dealt with by Ford as the incidents occur. I happened to be 30 miles from home when I heard a loud tapping coming from the engine compartment. Mechanic said he has done quite a few of these on the same engine. I also changed the wire set as well.
Now the only fix is to replace the head of the motor or even replacing the entire motor. Thank you ahead of time Did mine this morning in about an hour. Came close to rear ending another vehicle. When that happened, I brought it to Paso Robles Ford. If the failure had happened at that intersection, the failure would have probably resulted in severe injuries or loss of life.
My f150 has 117,000 miles on it and has had no mechanical problems over it's life. From what I understand Ford reduced the number of threads for the spark plugs to save machining time and costs in the manufacturing of the engine. The dealer advised that the engine head would need to be replaced. I'm not familiar with the set up of the engine compartments on the Sport models myself. It only took about 30 minutes to do the entire job and was very easy to do. Thank you for your consideration. I believe Ford should have done a recall or should compensate owners who had to pay large sums to repair this problem - Kathleen O.
I have tried to work with the dealer to get some sort of reduction in what I had to pay but they have been less than interested in talking with me. We were able to remove the broken plug and get a new one to thread maybe one thread deep to get me home safely. We both freaked out a little, she turned into a parking lot and jumped out of the driver's seat because she was afraid the car was going to explode! Essentially what this does is create new threads to prevent the spark plugs from popping back out. The current mileage was approximately 135,000 and the failure mileage was approximately 40,000. The failure mileage was 148,000. I took the truck to a repair garage who indicated that a spark plug had blown from the head.
The mechanic stated that I should definitely not drive it since it could cause a fire. Got out to check under the hood and all I could smell was gas. In August 2009, both rear spring were discovered to be broken when the car was taken in for a whining in the rear, which was the rear axle bearing. They may in fact come in from the top. I am somewhat of a Ford person and am not here to bash Ford, however I would like to clarify what happens in this situation.
