2001 Chevy Impala Idling Hard

Chevy Impala

my car is having all these symptoms. My car is
1. Idling hard
3. lights,radio,dashboard,turn signal is flikering or not working at times
4. when i stop it almost feels like its going to shutup
….I got owned u bought this car yesterday from a private seller….HELP!

First thing to check would be the battery and then the Alternator.
Is the battery light on or check engine light?

It sounds like the alternator has failed and it is trying to run straight off the battery.
