Best answer for 1998 Malibu Catalytic Converter
You have an engine misfire. At least it’s most likely. I own a 1999 Chevy Malibu with the 3100 engine. And the engine was shaking and the catalytic converter was red hot. Come to find out they it was the coil pack. Because when an engine misfires, a lot of un burned fuel gets dumped into the exhaust, causing the red hot converter. I am not saying this is what is your problem, but it very we’ll could be, because we practically have the same vehicle, and the same symtoms. Good luck to you! Your Malibu will run you years to come, because mine has 255, 000 miles on original engine and tranny.
