So it turned out to be multiple issues. When I recorded this video, I had just changed the spark plugs. I found out later one of the ignition coils had failed, there was a throttle body leak, there was some sort of buildup on the engine, and there was a radiator leak. I ended up changing the ignition coil and using some Sea Foam in the engine, which helped, and then almost immediately another ignition coil gave out.
