Check engine light: apparently something to do with where you put the gas in.... emission code; have noticed slight decrease in mileage, but still averaging 36-38 mpg city/highway. It is NOT due to the gas cap... the guy told me I would need to replace the whole 'unit' where you put in gas. I haven't.
