My 03 Expedition will not stay running once it as warmed up, and runs real rough. Local mechanic thinks its an electrical prob. Could be bad sensor.
High temp low oil light on, searched this light came back as thermostat? all gages read normal, it has the 5.4L with about 71000 miles.
Any ideas,any help. Wife wants her truck back.



Thanks, Mybigdogz

 

What engine do you have in it?

 

When was the last time you had the fuel filter changed?

 

Have not, will look in to that. Thanks

 

Have sent truck to FORD dealer. We will find out whats going on. When we called to get it in, they don't think its the fuel filter. They sounded like they know, or have an idea what wrong with it. We will see,will let everyone know. Thanks for reading

 

Lets see here, $385.82 later. We find that their diag's is, vehicle misses out on accel. and stalls at idle at times. The fix, replace alternator/harness re-program pcm.
They tell us we need to replace the wiring asy -A1063 part cost 36.28. Runs great, we are happy truck back on road. labor $322.00 Not mad just glad it runs.
Hope this helps someone else.
Now for that light, their telling us the Instrument Cluster {at $843.00} is going bad. Light not on now. undid battery to replace wiring asy. Reset codes. They say it will come back on, we'll wait to replace that. Hope this helps, Thanks for reading.
