i still have this problem.. when i want to accelerate fast the car hesitates, or you gotta help the transmission shift and let off the gas a little bit n then press again... but now i got an idea of what it is

Impala 3.4L

  • Automatic transmission
  • 127,500 miles

GM is aware of premature failure of catalytic converters for 3.4L motors. On another site it is reported that GM will offer some of the money for a catalytic converter ($595 for OEM part) for Impalas with less than 120k. Mine was 7.5k over.
