Question about 2003 Ford Expedition

1 Answer

2003 Ford Expedition intermittent engine/ignition failures

I drive approx 5-7 miles city driving each day, and from one to three times each day, usually when accelerating from a stop, the engine cuts out(stops) for around a half second or so, then it's running again completely normal. Three of those times in the last few weeks it died, but started back up without hesitation. When the half-second events occur there's no indication of a problem in the dashboard display, and there are no error codes showing in the computer. When it happens it's not a miss or a sputter like when an engine's running badly, it's an abrupt shutdown like an ignition problem. I've already eliminated an ignition key problem, it still happens using my spare key.

    If it was a fuel problem, it would "sputter" and try to keep running, but it shuts down like as if you pulled the coil wire loose, and within a second, it's back up and running 100%. It reminds me of the Ford electronic ignition modules, of which I've changed several.

This could be because of the fuel pump not functioning properly.

    Get the fuel pump and fuel injector checked.

    This could be due to the bad coil or spark plugs.

electrical is the weakest link-you may have a computer with issues and before replacin a reprogram should be considered--what did vehicle scan tell you? Data recorders are often placed in cars that show no codes--Older cars can have solenoids and components that heat up and stop engine--if theres a distributer cap-inspec for corrosion

2003 Expedition turns off while driving and check engine light stays on? Will turn right back on but 5 minutes later will turn off again?


When you have the service light come on all the time is simply indicates that there are detected error codes by the car computer that requires an attention.

It does not necessarily mean that it is a problem that will make the car not to run but you will need to get a scantoool to enable you determine what the actual issue is.

Please scan the car.

Cheers.

Ignition Distributor location


There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps
