Question about 2004 Ford Expedition
Will have to be scanned to find out what happened. Check your gas cap to see if you tightened it. That will trip the light but will go out after a few driving cycles after it is tightened.
A lot of part stores will scan it for free and tell you what the code is.

The Service Light indicates that the EMC has detected and problem and needs to be addressed. Your going to have the get the Blazer scanned for DTC codes which could be a simple problem as to a faulty Gas Cap to a bad O2 sensor.
Sorry can not help you more then this but most large auto parts store like Auto Zone will scan your blazer for free and some auto shop charge as low as $10.00 to scan and reset the ECM.
Good luck and hope it's something simple.

SOURCE: Service engine soon light it on
it could be both but im guessing that you changed the oil before the exact time for it to be done . if so have some one reset the light for you im not sure exactly how to do it on the 03 century if you have the drivers manual it will tell you how to reset it.
