sevice engine light
There may not be a problem because some lights are set to turn on at certain mileage intervals. One easy way to find out if something is wrong is going to an auto parts store and having them use their OBD hand scanning tool to read if there is an engine diagnostic code being engaged by the engine.
agreed,have a scan done,auto zone will scan it for free,get a printout of scan, for possabel problems,its not always what the scanner reads.
Ahhhh maybe your engine.
