We had an old nissan cabster where I worked in Aberdeen, it had petrol engine. One of the old guys thought he'd have a laugh and scare some of us young uns. He came wheeling in about the workshop door one day and had shut the ignition of but kept in gear with foot full on the throttle, he was going to give us a backfire scare but it blew the exhaust to bitsI found the leak!

So I'm driving down the the highway minding my own business when a slight hill caused the engine to miss (I'll ignore the 'why' for now).
The detonation was ... hard to ignore
