I took the dog for a walk and 20 minutes later the kitchen (!) still reeked of exhaust. That's when I pulled out my handy little carbon monoxide reader and found that carbon monoxide was spiked in the kitchen. Also in the garage, slightly more so.
Please remember that the smallest amount of carbon monoxide can cause brain and heart damage. I did a lot of research on this when I wrote the article and I feel very strongly it's the most underreported cause of heart attacks and strokes, despite being heavily studied in the auto industry for many decades.
I used an electric leaf blower to blast the carbon monoxide out of the garage and my meter went back to 0 quickly. (No, did not use the blower in my kitchen!) That is one of the fastest ways you can clear toxic gas. Opening the windows and doors takes a lot longer.
