    UPDATE TURNS OUT ONE OF THE NEW FORD MOTORCRAFT COILS THAT I PURCHASED FROM THE DEALER HAD MALFUNCTIONED SOMEHOW AFTER WE INSTALLED IT AND WAS CAUSING THE PROBLEM, IT ONLY TOOK THE DEALER A WEEK TO FIGURE IT OUT AND THEN STILL CHARGE ME FOR THE PARTS THEY PUT ON THAT WERENT NEEDED AFTER ALL. SO CHECK ALL THE OBVIOUS EVEN IF IT DOESNT SEEM RIGHT,
  • Yesterday we bought a '01 Ford expedition from munday ford that already had 153k miles on it......it ran so well yesterday and this morning. But leaving work for lunch this afternoon it will only start and stay on if I give it gas, and it such low RPMs. If I take my foot off it dies. Please help!!!
    Also there was no warranty on it from the dealership. So what can I do?
  • mine did that too. Its the central junction box. its the one thing ford overlooks. they had to hook a "heart monitor" up to mine and had one of thier mechanics drive it for a week til it miraculously died on him, they hit record on this machine and found the problem. Good Luck.
  • central junction box. trust me. there are no codes and ford doesnt check it.
  • I have 194k miles on my '03 Ford Expedition and just recently started to have some problems. When idling, the vehicle begins to rev up and down and will eventually shut off unless I put it in neutral. I have had bad vacuum lines replaced as well as several other things and still no solution. I can not tell if the vehicle shifts poorly in low speeds or if there is a lack of power from somewhere. Also, it is very sluggish in reverse as well and will shut off if I don't quickly put in back in park or neutral. I am not sure if it could be a problem with the fuel filter/pump or if it is a faulty coil. I have read on the message boards for a solution but still have not found one. Any ideas??? Thanks
  • How about checking out the IAC (idle air control) valve? In other threads I've seen it show up as a culprit.
  • I have a 2003 Ford Expedition that has been having problems for over a year. While driving, it randomly loses the power in the gas pedal and then dies completely after a couple seconds. It takes 3 or 4 tries and then restarts every time. It will be fine for a week and then it does it 3 or 4 times in one day. I took it to ford and they guaranteed it was the fuel pump. I then took it to a mechanic that was referred by 3 people and he said he did not think that was the problem (he did some readings for pressure or something). He kept it for a couple days, drove around and of course it never did it and he was stumped on what is the problem. I took it home and dealt with it for another month and then said forget it I will just change the fuel pump. Ford was going to charge me $1,100 but he did it for $800 and told me again he did not think that was the problem but what was I to do. He changed it and it worked like a champ for 2 months (which was longest it has went without happening) buuuttt...again..it is doing it. We tried checking the wire that sits on the a/c pipe but that is just fine. I don't know what to do. I can't take it for long trips and I can't afford to just keep "trying" stuff. Anyone have any other idea's? Help
  • Let me know what you find out because I have replaced everything including the cats 2 times now and still have *@!$% codes for the exhaust and the stupid P0171 code as well.

    I am so sick of this truck - I am ready just to let it go back.
  • check the coil boots, any condensation build up will cause those problems. the reason for that is the Triton design, plugs sit almost flat on heads, easy for water to be stored. solution: use electrical grease in all your connections: injectors and coils.
  • For cruise control problems, there is a recall on many F-150 & Expedition models. check if yours is one of them.
  • There is no fuel pump pressure gauge, but the fuel pump regulator is by
    cyl. # 8. diagnose: key on engine off X reading. when the engine is running it should be 5 p.s.i. less of your first reading.
  • I have a 2003 Ford Expedition as well, we have now replaced sensors, coils 6,7, 8 the fuel pump, I tried having the controller module re-programmed today, we will see if it runs better tomorrow. The manager at the dealer told me drive the car at least 30 miles after the re-prgramming and if it still does it to bring it back, that it could be the harness or chaffing of the wiires.

    Someone help ? Any ideas ?

    my 2003 ford expedition 5.4 engine has been hesitating, losing power and rpm not getting any higher than 1400 when accelerating. seems like engine boging down and has been stalling during driving for the last few days. engine light came on and code shows cranck sensor. cranck sensor changed with no luck. i have changed 4 of the eight plugs and coils in the past which has helped when the vehicle has been hesitating in the past. now ford diagnostic tests says may be cpm. i am a woman and not very familiar with all of this. what does that mean? Please can anyone help? ford has had my truck for 2 days and cant tell me a thing. just says it is a very unique code and they dont know why. HELP!!!

    My Expedition just turned over 110k miles and started doing this tiny little shudder/chug at idle and occasionally at highway speed. I also noticed that my fuel mileage was getting worse and worse. I changed the fuel filter and was told by several mechanics that the spark plugs likely needed changed as well. I had that done yesterday and the vehicle drove great the rest of the day yesterday and this morning. However, this afternoon I took it out and felt a tiny shudder as I was driving. I ignored it until I went to turn a corner and my vehicle died. It was still rolling so I put it in neutral and tried to restart it. It started and started and started even though I had let go of the key but didn't fire/actually start. I finally got it off to the side of the road and had to have it towed. I tried to start it twice more at the dealership but I got the same thing...it kept turning over but wouldn't actually start. It will be Monday before anyone can even look at it.

    Last summer my anti-rollover kept kicking on at random times and almost always when it rained. It would make my anti-lock brakes kick off and on and the anti-rollover light would kick on but only once did it throw a code.

    Is any of this related or just two random occurrences? Any ideas on the issue I'm having today?
  • I just let my expedition sit for about a month while I drove my other vehicle. When I started it again it started fine,but when I put it in gear,it stalled. Then when I gave it gas it would go ,then lose power,until I let off the gas,then it would go again when I gave it gas. This now happens in 5-7 sec intervals. Press gas it goes,then loses power,till I let off gas,push gas again and it goes.again and again the whole ride. So very annoying. Does anyone know ant the problem could be??? Pleas let me know. Thanks
  • I would be inclined to say to look at your Idle Air Control (IAC) valve. I had a similar issue with my 2006 Expedition, so I unplugged the battery, sprayed cleaner into the throttlebody and wiped clean around IAC, let dry and problem went away. It took a while before a light even came on, any many other people have stated that they had the same issue with no warning light at all. This was done about 25,000 miles ago, and still running strong.
  • Thanks produce guy. I'll def be trying that. I've also been told it could be a sensor and to use c foam(not sure if that's how u spell it) and spray some in your intake ,alil bit in your oil and the rest in your gas ,and its suppose to clean all the sensors and all that nasty stuff out. Not sure if you have heard about that,but I'd def like your input if you have. Again thanks. I hope this fixes my problem

    It's Sea Foam and I've read mixed reviews. No personal experience using the stuff. Sea Foam Motor Treatment. If you search around for it, many people (including me :blush: ) spell it Seafoam.
  • I've Sea Foamed my '03 Expedition about 20k miles ago @150k, but not my '04. I did the "through the brake booster" technique. I think it definately cleaned things out - it was a smoke storm when I restarted it, but that is what you are supposed to get. After the soak and start through the booster, I did a can in the gas tank. Not brave enough to throw it in my oil. I've got a pair of cans to do it again, just haven't had the time.
