1999 Ford Expedition: engine knocking or ticking

Filed Dec 2, 2015 · Engine · 187,000 miles · TN

The spark plug blew out of the head while I has just pulled out accelerating up a small incline. I was going through a major intersection with my son. There was a stutter, then knocking sound, less power, and strange odor.

My expedition started acting like it was starving for fuel misfiring loss of power and there's a ticking sound coning from under the dash board the door lock unlock the lights flicker and horn beeps by its self I parked it and a couple days later it wouldnt it trying to crank but its sound I dont believe battery is dead if it was then lights wouldn't come on now and again also when I use my key ring lock to lock the door there's a clunk cluck sound I've spent a lot of money trying to find out what's wrong with lamont that's my expeditions name and nobody knows last repair shop had it 9 days total on the 7th day I called them they said they had no idea and on the 9th I went in and they said I needed a new motor costing 2600 and charging me 220 to tell me that. The shop before that cost me 350 saying the truck itself were the plugs go in was stripped and they needed a special tool. Any how I believe it would be a matter of time before the vehicle will catch on fire. The vehicle is very unpredictable and you dont know what it will do next it also dies while driving it ..

I bought this used 1999 ford expedition 5.4l and noticed a knocking first time and saw that the #3 spark plug had come unscrewed from inside, then as I replaced it the #4 came unscrewed, re screwed it back in and now the obd ii codes came up the spark plug was no longer good, as I have wanted to change the spark plugs all new I am unable to screw back in a new spark plug in #4 spark plug hole. I didn't know that spark plugs could unscrew on their own till now. I believe ford if they knew about this problem in the first place they should repair at their own cost for something they knew would happen.

Heard a knocking noise coming from the engine department, took said vehicle to a dealership to be checked out, was told that it was a leaking exhaust manifold, I then checked what I was told and did not find any problems with the exhaust, then three weeks later without warning the no. 3 cylinder spark plug ejected from its port and breaking the ignition coil assembly, as of now, we are trying to figure out how to fix said problem because I have researched the issue and see that ford does not have to fix said problem.

Was driving car to work this morning. Made a right hand turn and heard a knocking noise suddenly after completing turn. Pulled to side of road and immediately shut down vehicle. After shutting down I smelled what appeared to be gasoline. Called my insurance company and they had vehicle towed to ford dealership. After waiting a few hours they told me spark plug had popped out and cylinder head needed to be fixed along with plug, and it was indeed gasoline I smelled. They said it would need major repair to fix, and tried to convince me to pay and arm and a leg. I don't care about that, I care that my child could have been in car, as I pick her up every day from school. Also mad that a fire could have started and ford does nothing about this problem and that there have been thousands of complaints from ford truck owners with expeditions and f150's from 97-02. Something better be done to recall these faulty engine components, or families will suffer from ford's lack of safety with these plugs and cylinder heads/coils.

Two weeks prior to this failure, there was a distinct ticking noise that changed with RPM. Sounded like a collapsed lifter. While returning home on memorial day 2008, experienced a loud popping noise, followed by continued whoosing noise and poor engine performance. After inspecting engine, noticed #7 spark plug had come out and broken the coil-on-plug coil unit. Failure occurred 2 blocks from my home, so I limped it home. Have not had it repaired yet.

I purchased my 1999 ford expedition used, with 50,140 miles on it. I also purchased an esp warranty plan. My engine always had a knock when cold.I thought that was "normal". On the week of april 12th, the engine knock became severe and the vehicle had been using more oil than usual. I brought it to johnson ford for repair. My service advisor told me not to worry, I had the best warranty plan there is, and that this is a very common problem with the 5.4 engines.he even told me that he spends much time calling in similiar claims. The diagnosis was "spun rod bearings". After two weeks, my claim was "denied", and I removed the vehicle from the dealership after a $6400.00 estimate for a new motor. I brought the vehicle to a reputable independent, and had to purchase a used motor for my ford. After much research, I have found that numerous people have had complaints about defects in the 5.4 ltr engine. I find it very frustrating to have spent $1100.00 on a rental car, $4300.00 on repairs, and $335.00 to johnson ford to tell me that my engine failed. (I knew that when I brought it in!) in addition to that, I spent $2395.00 on an esp warranty that was of no use to me. Johnson ford is claiming that my engine failure was due to lack of maintenance. Mobile tech (the independent) has stated that my engine was sludge free, and that their opinion is that is was not lack of maintenance. I have written at least 20 letters to the dealership, the bbb, and different departments of ford motor company since april 30th and am getting no answers or satisfaction. The motor remains at mobile tech as I have requested an examination, again, from ford motor company. To date, I have been repeatedly denied my request.

Engine problems, I purchased a 1999 ford expedition 4x4 used dec. 21 2002, in feb 2003 I had to take it back to the dealer for a head gasket problem, had to have that repaired, after that was repaired while still in the shop the mechanic couldn't get it to run smooth. I was told that it was missing and was barely running, it would hardly take off and once you got rolling it would spit and sputter and cut off while driving down the road. I finally got it back 2 weeks later, when I asked what the problem was I was given the response, we don't know we just replaced parts until it was running smooth? What kind of answer was that? Now here it is aug 2003 and the engine is knocking! I took it straight to the dealer and they said yep sounds like you've got either a bad bearing or some kind of rod was bad???? Hello???? Then I was told to bring in back in a few days that they couldnt inspect it completely at the moment. Then I was told not to be driving it, ok how do I get it home if I cant drive it? How do I get it back in a few days if I cant drive it? I paid a lot of money for this piece of junk, why should I pay $20,000 for a vehicle and have to pay another $5,000 in 6 months just to be able to drive it again? Whats up with ford? Are they so hard up for money that they have to shaft their customers? Way to go ford!! Keep up the shafty work we all (customers) like to pay $20,000 + for a hunk of junk that we have to keep putting money into. I cant believe im paying payments on a vehicle that I cant even drive, that really sucks. To bad there isn't anybody that can make ford do something about those bad motors and all the other problems they are having, yes I work everyday to pay for this lemon vehicle and whats even worse is that I have to bum a ride to work, now thats sad with a nice expensive vehicle sitting in my garage.

Vibrating feels like from rr right side, at speeds of 50-60 MPH, driveshaft replaced 2 times, fixed slipped yoke 1 time, universal replaced by private garage trying to repair problem and frod dealer paid for repair but this did not solve problem. Rear transfer case has begun to leak, fixed once in feb 2002 and currently being fixed again. Odometer does not always come on windshield wipers have by themselves, back wiper only when it feels like it. Engine has idled rough and has stalled at very low coast (when parking) in both forward and reverse. Door ajar switch would not come on or go off when it did go on for length of trip. Ignition lock would not lock,and sticks. Right front door lock would not unlock. Driver window slams when going up. Clunking noise when shifting into reverse.ticking engine noise when starting vehicle. Most problems have been solved, but not the vibrating in rear end. This has existed from the time we bought the truck, we have been to 2 different dealerships, have been told slipped yoke, driveshaft loose, driveshaft unbalanced, and now the tires had debris in them, in which they had a put on a month prior to it being back in their garage for the vibrating. Ford oughta be ashamed of themselves for doing this and causing this kind of stress. I have 3 years left to pay on this vehicle and have been through almost everything with it, now that the warranty is up I get to pay for the same repairs happening over and over again?

Piston knocking and vehicle is losing power, and it stalls. Could be dangerous if on a highway. Consumer states at 50 MPH cars starts to vibrate.

Engine hesitates. Dealer was not able to locate problem or provide remedy. Also, vehicle had an oil leak, and knocking noise. Dealer replaced head gasket, but problem is reoccurring.
