What is a dead misfire?
What we call a “dead-miss” describes a complete misfire with no combustion taking place whatsoever. A partial misfire means there’s some kind of a burn, but significantly incomplete combustion. An intermittent misfire (dead or partial) occurs only sometimes, be it under certain conditions or indiscriminately.
