Can a distributor cap cause misfire?
The distributor cap should be inspected carefully to see how the sparks are arcing. The internal and external surface of the cap should be clean. It could short out the coil voltage and cause a faulty connection inside the terminal of the distributor cap. The result is a misfire in the spark plugs.

Why is my distributor cap not working properly?
If your car starts easily but stalls or backfires on the road, this is because your distributor cap is faulty.

With a crack, clogged or anything prevents the rotor from spinning, it will work only at a part of the time. 5. Difficulty Turning Over
How are spark plugs used to keep the engine running?
The spark plugs utilize the spark from the distributor to ignite the fuel mixture, which is what keeps the engine running.
