2010 Expedition EL, 38k miles.

The wife experienced some stumbling of the engine pulling out of our subdivision. Intermittent. I put in some super unleaded and fuel injector cleaner. Did a road trip from GA up to IN and didn't give it another thought.

Well, last week she's coming home from work and tries to start the truck. It runs for a second and dies. Subsequent starts, it tries to start but does not get going. I have her on the phone and tell her to work the gas pedal and floor it when it begins to run. It clears up after about a minute and runs fine.

I experienced this once or twice in my 2000 F250 once or twice but once running, it didn't do it again for a year or two.

Her Exp. has done this repeatedly for a week (i've been out of town). I am putting in the super concentrated fuel injector cleaner and a full tank of high test again and going to the auto parts dealer to put the reader on it.

There were no check engine lights or messages of any kind.

EGR valve or 02 sensor? That's my first guess but I would have expected some kind of error code or check engine light...

Thoughts???

 

If it were EGR related or O2 related, I would expect a code especially in a no start condition. If it were me having this issue, I would probably pull codes oike you referred to and if there was nothing there I would then most likely throw a fuel filter at it. A fuel filter would be short money.

 

Exactly what I was thinking. No codes. Started right up for me this am (go figure!). I'll put a new fuel filter in it and see what happens.

 

I had the same type of problem using gas from a" knock off" station. Filter clogged at about 25k.

I would change filter, and remove battery cable for 20 minutes then try that. I would stop using fuel system cleaner for the time being.

 

Dealer did a computer reset that appeared to cure the problem. About 2 weeks later it did it again. Typically does it when the fuel is below 1/2 tank.

Picking up a new filter tonight. We'll see if I can do this without breaking the infamous little blue clips!
