so my car shut off every time i turn it on.
i took my car for a battery change,n now my car will start but wont hold an idle on 2002 Lexus ES300
Jumpstart vehicle from another car. If it holds and continues to run, remove jumper cables and let vehicle idle for a few minutes. If the alternator is bad, it will "stall out" during this period.
