My battery went dead Saturday they (Auto Zone) said it was bad, got a new one, battery went dead again Sunday they (Auto Zone) said it was my alternator got a new one Monday. Got in the car this morning, got on the highway ck engine light starts blinking try to accelerate and car revs up but no go, battery starts going dead. Make it the couple miles home and the car is dead no lights nothing when I pull in the drive. Any ideas?
