I had the same problem with my 01 Impala and had to replace the catylitic converter worked like a charm I also had the same problem on my 01 and the Cat was plugged and then changed out, ran like a new car after that If you car is under 80,000 miles and less than 8 years of age GM will replace it for free as it is covered under the emissions warranty. This happened to mine at 75,000 this week and it now has power like it has never had before.
