2004 Chevy Impala Keeps Stalling

2004 Chevy Impala LS 3.8L

Shortly after starting the car while parked or driving at slow speeds I will loose all electrical power to the vehicle. Inside the cab I lose power steering, brakes and dash power all within 2 to 3 seconds and the vehicle stalls out and shuts off. I have had the alternator and battery tested by AutoZone and they both passed with flying colors. While testing them the car did turn off and according to the AutoZone rep there a was a puff of white smoke rising from the bottom of the engine compartment. The car drives and operates normally except for this. Autozone did run the DIAGS on the car and didnt report any codes.The car does this at random and is never predictable

P0171 and P0174 are lean codes. There is likely a large vacuum leak or the MAF is bad.

Try starting the car and wiggling the connector for the MAF sensor. Also try tapping the MAF sensor. If the idle changes or the car stalls replace the MAF sensor.

The second shop should recognize that these codes don't have anything to do with the ignition module.
