Runs rough and stalls


Asked by Michael Sep 30, 2017 at 01:40 PM about the 2005 Ford Expedition XLT 4WD

Question type: Maintenance & Repair

Truck runs rough and stalls when coming to a stop
after it warms up. I have a list of all the codes. I
have tried to add photo but it fails. So the codes
are as follows:
P0171, P0012, P0305, P0345, P0430, P0743,
P0300, P0340. I will try to attach image soon.

With the number of codes thrown up I'd reset the fault codes and see which ones return, often it's one error causing other sensors systems to go out of normal range. If all of the errors keep coming back it's most likely a wiring or earth issue and you'll need to track down the common earth or the location the wires from these sensors all pass through. Then again it may be something as simple as a dying battery or alternator as a low voltage situation can throw up all sorts of random error codes.
