I have changed everything under my hood: battery, alternator, plugs, wires, mass air flow sensor, muffler, and coil pack. Still, I'm having trouble with my 90 Olds Toronado Trofeo.

The exhaust pipe is heating to an orange glow (HOT!) from the catalytic converter to the muffler. Feels like all of my cylinders are not firing. It's robbing my car of it's efficiency and power. Can you please offer your professional opinion? I would love to get my car back on the road. Your help would be greatly appreciated.
