I have a carbon monoxide detector set up in my garage. It's been very reliable. Can't get the thing to shut up when the Wife's Buick is in there, sitting at idle. Never once went off with my truck in there. Ok so that just means the exhaust is doing it's job... but then where is that sickening smell coming from?
An incorrectly timed engine, running poorly sends hydrocarbons (unburnt gasoline vapor) into the converter, poisoning said converter, burning your eyes, and producing a rotten egg smell. Excess HC is not CO, therefore the CO detector is still working.
