i had the light come on too and i went to AZ so they could text it and they said i had a bad battery and and bad alternator. they said sometimes when an alternator goes bad it takes the battery with it. i replaced the alternator and the battery is still testing bad..
im not sure what to do considering the car still startes and drives.
i was told a bad battery can cause low idle and hard starting sometimes, and SOMETIMES my car is hard to start (takes a sec or 2 longer) and has been idling a little low for about a month or 2..
what to do??
