Generally this turn on when have any problem with the emission sensors; to know excalty what fault code there, make one scanned the PCM in autozone or autoshop with OBD Codes Reader.

With this code number we could send aditional details.

Hope helps (remember to rate and comment this).

SOURCE: misses during acceleration , rough

Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.

It does not take 3 hours to change spark plugs..I will suggest you get the right equipment to do this job.Get the right tool that can sit on the spark plug and unscrew....You will need to disconnect the coil pack that sits on top and disconnect the wires if needed.From there it is self explanatory.

SOURCE: Grand Am 2003 "service engine soon" light

The service light means something is wrong with the car and it needs attention now. Get the codes checked and that will tell you what is wrong with it.

Take it to your local mechanic to get an OBD code check. It should tell you the problem, and you can get an estimate on the fix unless you want to do it yourself. It could be a fuel filter issue.

What is the meaning of CHECK ENGINE ZONE for my ford expedetion 2003 v8 gasoline


http://www.ford.com/owner-services/customer-support/ask-ford-faqs?qtype=uq&inputtext=check+engine+zone

http://www.motorcraftservice.com/pubs/content/~WO3EXD/~MUS~LEN/41/03exdog5e.pdf

I checked the manual for 'CHECK ENGINE ZONE' and could find no reference to this for the 2003 Expedition.

There is a Service Engine Soon light though.

I looked all over the manual and could find no instrument cluster light to that effect.

Can you tell me what page refers to this?

Service Engine Soon light came on


This means it's time for a service..But have it diagnosed with a computer and maybe sometimes resetting it solves this problem.If the light comes back again then you need a servicing of the engine.

Service Engine Light staying On


Alot of times a voltage drop to the O2 Sensor can cause your check engine light to come on. Even tho the O2 sensor is wrong fine.
