Zero to 60 acceleration with a clogged catalytic converter

Описание: March 17th 2018 drove my grandmother's Impala and figured I'd do a 0 to 60 test with it and I thought the transmission was going out on me or slipping so we took it to the dealer and come to find out the catalytic converter was clogged which is why the car was acting up and was late on its shifting or felt like it wouldn't shift unless you let off the gas
