Loss of Engine Spark
Damaged, worn, or bad spark plugs, or a weak ignition coil can cause a loss of spark, and therefore, a misfiring cylinder. This may happen periodically at first, but as components in the ignition system continue to fail, you’ll notice an increase in the number of misfires.

It’s 25% on a four-cylinder engine, 17% on a six-cylinder, and 12.5 percent on an eight-cylinder.
How long does it take a misfire to damage the catalytic converter?
Any raw fuel in the catalytic converters quickly overheats them and leads to their destruction. If misfires occur severely then damage occurs quickly. If misfires are subtle, then damage may not occur for a year or two.
