Well it's misfiring. Unfortunately there's dozens of things can do that. You could have a blowing head gasket. You could have bad fuel injectors. You could have a weak fuel pump could have all kinds of problems. I would advise finding a guy like me took up a scan tool and analyzed the data. It doesn't take us more in half an hour to figure out why it's misfiring. Just pray it's not something big like a head gasket starting to blow
