could be a cat converter clogged. you need another shop more familiar with driveability issues that can help you diag it and give you a bid.

Can it be unclogged? The PCM that was originally in the car was a 2002 it was replaced with a 2001 brand new PCM does it matter that the years are different or do they have to be the same?
