If talking to him doesn't work, I'd recommend calling the police non-emergency number. Some US states have laws against how long you can leave an idling car unattended.
He's out there with it, under the hood. Revving it, over and over. For hours.
If it was something like a lawn mower, I wouldn't care. Yard maintenance is necessary and people around here are pretty considerate about not doing it first thing in the morning or anything.
