Hello there, many faults will cause your 2006 Chevy Impala to have a lack of power. Without knowing what parts were replaced or the codes that the car had I am only able to provide a general answer. The most common faults are the spark plugs, coils, fuel pump, fuel filter, alternator, battery, vacuum leak, MAF sensor, or the oxygen sensor.
