had my brother, whose close friends with local mechanic, code scan it for free and when we first did the scan here were the codes: MAF problem, random misfire. Previous owner stated he had MAF sensor replaced recently, so we reset the codes and it showed misfire on #2 cylinder. Im pretty much set on the catalytic converter though, the engine is running pretty warm, the exhaust gas is REALLY hot from the mufflers..and this letter straight from GM:
Condition
Some customers of 2001-02 Chevrolet Impala, Monte Carlo; Pontiac Grand Prix; and Buick Regal model , equipped with a 3.4L (RPO LA1 - VIN E) or 3.8L (RPO L36 - VIN K) V6, may experience a condition where the vehicle exhaust catalytic converter is replaced due to complaints of lack of power or illumination of the Malfunction Indicator Lamp (MIL). This may be due to the front endcone insulation from the catalytic converter breaking away and blocking the front of the first catalyst brick and preventing the free flow of exhaust gas through the converter.
Special Policy Adjustment
This special policy covers the condition described above for a period of 10 years or 120,000 miles (190,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. The repairs will be made at no charge to the customer.
