I have a 2000 Expedition that seems to have fuel problem. Especially when I am driving at higher speeds or going up hill, it acts like it is running out of gas. I put in a bottle of Lucas injector cleaner but the condition seems to be getting worse everytime I try to drive it. I am wondering if anyone can enlighten me about what I can expect the auto repair shop to charge for this and what is the most likely cause of this condition. The 'check engine soon' light came on and off for a day or so and now it is staying on. A couple of weeks ago I ran it out of gas and this problem started after that, so I am thinking it is a clogged fuel filter or clogged fuel injection system. The car seems to otherwise be running really good and strong. There are no noises, smells or gauges pointing at anything else suspicious. Deb

I am the original owner of a '99 Expedition XLT (4.6L 4x2) and the car has been great except for the past six months. Has 126,000 miles. Main problems recently: - engine stutter/miss (intermitent) between 40-60mph - transmission fluid leak - thumping/moaning/creaking (from rear) when backing out of driveway and going over speed bumps - very low gas mileage (averaging 11 mpg even with 1/2 of miles on highway) I recently had it serviced: - for engine stutter/miss: technician couldn't replicate problem in test drive, but they tightened drive shaft linkage and the problem went away for a couple of weeks... now it's back. - for transmission fluid leak: replaced gasket at torque converter and driveway leak went away, but now I can smell that sweet scent of tranmission fluid burning off again just a few weeks later. - thumping/moaning/creaking from rear end: have not checked into it. - low gas mileage: have not checked into it. I have read many postings from this website about IGNITION COIL PACKS and REAR DIFFERENTIAL problems. Do the symptoms I describe sound related to these types of problems? Can low gas mileage be caused by these types of problems? Or should I expect 12 average mpg from a 9 year old large SUV?

Our 99 expedition won't start with the key from time to time the theft lights go on and it won't turn over, someone told my husband to start it three times real fast and it'll start, it worked, until yesterday, it won't start at all. What could be the problem?

Replying to: togden (May 29, 2008 12:17 am) Engine studder/miss: Assuming you don't have the check engine light on and there are not codes showing on the ODBII port read out the missing is likely moisture inside one or more of the coil pack rubber boots or a faulty coil pack. Pull the coil packs and check for moisture inside the spark plug tube or the spark plug boot. A good indicator will be corrosion on the spark plug. Next, if you've never changed the plugs do that next. If it still misses buy a new coil pack and change the coil packs out one at a time with the new one to see if you can eliminate the problem. Try the #3 hole first. That one seems to be a problem area. Its also the most common blow out hole (these engines suffer from spark plug blow outs). Transmission leak: Add some flourescent die to the transmission fluid and run the vehicle until the transmission oil temp is up to normal. Shine a black light around the tranny until you can identify where he leak is coming from. Then trace is back to the source. Rear end noise: This one stumped two dealers around here. The problem for me ended up being the shock mounting bolts. Over time the holes get oval and the bushing ends develop play that only shows up when the rear end is articulating. The only way I found it was to put the vehicle up an a lift and with a couple of friends shook the rear suspension up and down as hard as we could. (btw - make sure your spare tire is tight in its mount. This also causes a clunking noise if its loose). Replace the lower shock mounting bolts with new ones. If you haven't changed the shocks in a while now would be a good time. Especially, if the lower shock bushing are shot. Low gas mileage: This is probably directly related to the missing. The first culprit here would be the mass air sensor. But, if you don't have an engine check light on and no codes showing then this won't be the problem. Check the mileage after you solve the missing problem. Borrow someone's ODBII code reader and get a read out from your ODBII port just to make sure you don't have a problem with a sensor. (i.e. an oxygen sensor could be going bad). Hope this helps. |

Here's one for the books -- can't find a TSB on it either. '04 expy EB with the rear climate control system. When I set the dial in the 1st and 2nd positions for rear ventilation, it makes two different sounds behind the middle seat on the passenger side. In the 1st position, it clicks, 2nd position, it makes a "whump" sound. Position 1 is "click, click, click..."; position 2 is "whump, whump, whump...". When the rear dial is returned to the "off" position (farthest to the left), it goes away. Also, if I set the vent system to "floor", it disappears. On the higher level setting, it comes back. Sometimes it goes away, other times it does not. Is there some sort of a vent regulator behind the passenger side middle seat? If so, does anyone know what this is, if there is a TSB or is this just one of those weird items no one else has experienced?
