Why does my car keep blowing ignition coils on the same cylinder?

Repeatedly blowing and melting ignition coils and plugs on one specific cylinder usually points to a localized fault such as a shorted fuel injector, a wiring harness issue, or a compression problem feeding excessive heat to that spot. This prevents the vehicle from running reliably and causes persistent misfires even after replacing the parts.
