Will a dead cylinder cause a misfire?
A loss of spark is another symptom of a misfiring cylinder in an engine. This is usually when the coil voltage can’t hop over the gap on the spark plug end. Bad, damaged, or worn spark plugs will cause the ignition coil to weaken, resulting in a cylinder misfiring. This should stop after the engine has warmed up.
What causes a dead misfire?
Causes include worn, fouled or damaged spark plugs, bad plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder. Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited.
What causes a misfire in cylinder 3 and 4?

How do you fix a dead misfire?
Inspect the spark plugs for signs of damage. Use a spark plug socket to remove the plug so you can get a good look at it. The damage you see will help you determine the cause of the misfire.
