Service engine soon light on,2003 Vue,6 cylinder,awd,automatic,24 valve engine

Continue driving for a few more days.. Can always have scan test.

I think the solution for your car is to preform a " DRIVE CYCLE " replacing the battery reset the " I M 's " as you know Saturn has two service lights. the light that says "service engine soon " is only related to the " smog system " the light that says service with the wrench symbol deals with the rest of the car. if you can get your hands on a code reader that can check for I M readiness you can find out which im is not set and make the pcm do the test to clear it. i think you have probably fixed yours but i hope this helps others happy motoring
