Have you done a tune up? That's where I would start. Plugs, wires, cap and rotor, fuel filter and all that jazz...

Thanks guys for the quick response!
SES light has been on for years for O2 sensor. Have not had tune up for over year. All was well until left car for 8 days on vacation.

DIAGNOSE before blindly replacing parts! What is the code? Have you checked the OBD2 code section for a run down on how to diagnose the code?
