'03 EB w/ 118K miles, owned it since 80K and have only replaced the batterry, tires, and brakes. Normal wear and tear items. It doesn't like to start on the first turn of the key but always starts after two or three trys. Mechanic said that's a Ford thing not to worry about it, second opinion said it could be fuel pump control module? wanted $900 to replace it. I don't have $900 laying around so I'm going w/ the first opinion.

2 expeditions at over 120K
One's an 03 and Mine's a 97 both have had no engine work

front end on the 97 is GONE! that just happened friday... something up there is Effed.
97- Air to coil, new caliper, brake pads, slow freon leak (charge lasts me about 3-4 months) and a body lift lol.
It does have an engine miss but it never stalls and has no shortage of pulling power in the low end
03- New front rotors, brake pads, window regulators, has a massive AC leak when you turn on rear air (never turn it on and problem solved!)

Used to have a 98 with 250K on it then the bottom of the spark plug seperated or something like that and shot into the farthest back cylinder. My dad literally gave it away in 2005... broke my heart. Then he got another one haha

over all pretty reliable trucks, my next vehicle will not be an expedition, however it will be a ford!

2003 5.4L, 154,000 miles

I get approximately 19 mpg with cruise set at 70. I hardly ever go faster than that. If I see a tractor trailer then I draft behind him, and even at speeds above 75 mph I'll easily get over 24 mpg while drafting. If I back away from the draft at that speed, the mpg drops way down to about 17 mpg.

I bought it last year with 135K miles. I've only replaced standard tune up items and 2 COP's. I'm in the middle of a possible tranny problem, not sure yet.

I am at 260K but just bought it about 2 months ago from a 12 year owner and was told no major work done to it and was a fleet truck for the first two years. I am skeptical on that as my trans shifts like its tuned or something and I was told it has only been serviced many times. Fluid looks new in it. I know it is not tuned since I just did a Superchips tune today so not sure. Lol! It does need the cracked manifold replacement which is next on my list.

5.4 l

Our Expedition is a 2009 XLT We bought 2nd hand from a dealer.
It currently has 33,000miles on it so far we have had to replace the water pump, s seal on the front diff Rh side and the 1/2 shaft. As well we had a paint/sheet metal issue on the rear lift gate. Also a sensor (bank one catalyst monitor. So far all have been covered by factory warranty. I have noticed other 2007 to ? with bad paint and or sheet metal on the litft gate.
They must have a hole in the roof at the plant where some units sit overnight when the line stops for the day.

97 EB 4x4 with 5.4L and 4R100 trans. Bought with 144K and a bad rod knock for $800. Reman 5.4 from marshall engines (via Rockauto), runs great, no hidden issues. 19-20 MPG at 70 MPH out in the open. Just did forst oil change with Mobil 1 5W20, will see if it improves. K&N cold air intake kit bumped it up from 17-18 MPG at 70MPH.

2004 130,000 miles just had my right front air suspension go out, so i did the strutmaster converstion kit. cost me a ton..... I got the deluxe with all the extra new parts, but 900 for the kit and 800 in labor that is right $1700 in it now. but I will say it drives great. super tight and looks and rides alot better.
