Ford Expedition engine cutting off while driving

  • I have a 2005 that cuts out on take off this usually only occurs when building speed to get up to hiway speeds of 60 or so. Never cuts out in town or city driving always only when accelerating once cutting out starts I push the gas hard and it comes right out of it then runs fine until I slow down and have to accelerate again. This thing has got me stumped. I did air filter change, injector and fuel system cleaner. and no change...please help....
  • How many miles? It sounds like a misfire. Do you have a check engine light? If not you may want to have a place with a good scanner read it for pending codes. It will likely show the misfires and what cylinders are doing it. From there I would look at plugs and COPs.
  • 114,000 I did an ohm reading today on cop's all read between .07 and .08 except for one, and it read .06. Which tells me that would be the one to replace if any. Also went and had it put on machine "no codes found", they told me if it wasn't a misfire that is constant it might not throw a code". also I found today that if I take the overdrive off the miss is still there but not as noticable. is this normal? I thought maybe tranny issues since the overdrive calmed it alittle, but this thing is a smooth shifter, and no slipping of any kind almost seems like it has to be a cop? whats your thoughts?
  • I still think it is a classic description of a bad COP. Where did you have it scanned? A discount store will not be able to read pending codes, where a dealer can. A misfire may not immediately set the CEL but will be logged in pending codes.
  • The engine would stall once only every 3 or4 months or so and crank back up right away, but yesterday it shut off 5 times while my wife was driving and that means "fIX RIGHT NOW"
    I found the wire chaffed completely to the copper right where you said it would be on the A/C tubing near the battery and I taped it up and repositioned it so as not have the problem reoccur.
    Thanks a lot

    After a few scary incidents of our 2003 Ford Expedition shutting down (including on the freeway) it finally did not start. Although the engine turned, it appeared it was not getting any fuel. I had an ASE mechanic look at it and though it was the fuel pump which I ordered for $160 from rockauto.com (ordered on a Friday and received on Monday!). The pump was replaced but it still didn't start.

    He then looked at the fuse junction box and it appeared to be burned out. In my research, I found the following:

    The original Fuse boxes installed in these Trucks had 2 major problems. The First is the windshield leak problem. These trucks had a bad seal from the factory that allowed rain to drip down on the passenger side of the truck at the bottom corner of the windshield. The water leaks directly into the fuse box, ruining the circuitry

    The Second problem is just a poorly engineered part when the car was new. These circuit boards were poorly made, and after a few years of heat and cold, the relays fail to function any more. There are no repairable parts in this fuse box as all the relays are soldered to the circuit boards; the whole fuse box must be replaced.

    Also, in speaking with my local junkyards, they can't even keep these in stock due to this known problem.

    The part (Ford Part # 3L1Z14A068AA) was $371 plus tax from my local Ford dealer however, I found the box for $260 (no tax) and paid for two day shipping for a total of $300 from Olathe Ford link title. PROBLEM FIXED within minutes and we are now back on the road.

    Hi im having the same problem with my 2003 ford expedition. Did replacing the fuse box fix your problem for sure? I've already put in alot of money and work into mine so was wondering if it fixed the problem on yours. Please help
  • no it did not. Basically I took it to Ford, they kept it for a week to find out where the problem was, and it was in the wiring harness, melted. They wanted $1500 to fix it and they still weren't sure if that was going to fix the problem.

    My wife has an '03 Ford Expedition with 110k miles on it. It began dying while driving. Usually when stopping or idling. She would describe that sometimes when it began acting like it was going to die she could "give it gas" and it would revive, other times that wouldn't work. It would usually restart after one or two tries. Our local mechanic did a tune up and replaced a coil. During a trip she began hearing a sound of "metal shredding" and the car died and wouldn't restart. She had it towed to a Ford dealer. They replaced the IAC valve. After that the dying would continue but instead of dying right away it would "lose acceleration, and eventually die within a few seconds" Took it to another Ford dealership and they replaced the fuel pump, filter and relay. It would work fine for a few weeks and then start dying again. Another local mechanic noted the error code P0231 "Fuel Pump Secondary Circuit Low" He kept it for a few weeks and was able to get it to die for him once but not again. The dying continued. Sometimes it would work great for weeks, other times it would die continually on the same trip. Took it to a 3rd dealer and they couldn't find anything wrong. It dies in the cold and in the heat. Usually after driving at least 20 minutes into a trip. Once it dies once it will typically continue to do so until resting for a day or so. Sometimes with a full tank of gas, sometimes with a low tank. Any ideas?

  • johnm32, What you describe is the exact issue I have with my 2003 Lincoln Navigator with 180k. I HAVENT attempted any repairs and or replacement of parts yet. After it dies, I typically wait 30 seconds and then it starts right back up. If I attempt to start it immediatley after it dies, the motor just turns over but wont start (must wait about 15-30 seconds). Some days it will die only once, other days 3-6 times all within an hours and then it seems to be good. It may drive fine for days, maybe a couple weeks before it dies again. My idle is only about 650 warmed up, not sure if thats where it should be for this vehicle but seems a bit low to me (could be why the motor seems a lil bit ruff at idle...? not bad but just slightly.... I havent checked the battery wire along the AC line everyones refering to and I havent looked at the fuse panel issue...(i guess the fuse panel is same in lincoln navigators as it is ford expeditions) My shade tree theory was that "maybe"...just maybe, seeing as I have to wait a half minute or so before it will start back up (I typically leave the iginition key on during this wait time) that maybe I am loosing fuel pressure and with the ignition key on, it allows the pump to build pressure back up, allowing it to start up again. Just a theory and not a diagnoses......? I guess I will start looking over some of the things mentioned here in hopes of saving some coin.
