#96 of 113 2003 Ford Expedition Engine Problems
Dec 07, 2011 (2:37 pm)
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 ?

Jun 25, 2012 (2:58 pm)
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!!!
