'03 Chevy Malibu occasionally losing power when coming off of the highway/slowing down at red lights. As long as I am driving above 35 everything seems to be okay. Had it taken into the shop and the only codes showing 0420 for the cat converter. I've read about other malibu owners having this problem and not being able to find any solutions. Oil and trans fluid were just recently changed and serpentine belt was just replaced. This happened about a month ago after a 3 hour trip on the highway and then the vehicle was fine for 3 or 4 weeks. Happened again last week but when the car was at the shop and mechanics were test driving it the problem never happened again.

SO, I know for sure I'm going to be trading in the ole Bu. My question is to others who have experienced this problem, how far did you make it after this problem started happening? How many days/weeks/months was it before the problem appeared again? I just want to get her the 2 hours to the dealership without breaking down.
