just like the title says i just bought the car from some old guy telling me that it didnt have any acceleration. He said it was b/c the catalytic converter was clogged. i get it home and from what he told me i i just cut the cat off ran it straight figured it would have accerleration. still doesnt have any just noise as hell. anyone have any input of what i should look for or check?? any help would be appreciated thanks
