In Addition to Flashing the MIL, How Do Many OBD

Multiple Choice

In addition to flashing the MIL, how do many OBD II PCMs react to a "Type A" (severe) cylinder misfire?

A) The PCM turns off the spark for the misfiring cylinder.
B) The PCM turns off the fuel injector for the misfiring cylinder.
C) The PCM increases fuel delivery for the misfiring cylinder in order to allow the extra unburned fuel to cool the catalytic converter.
D) The PCM energizes an oil solenoid which allows a specially designed lifter to collapse, resulting in keeping the exhaust valve closed so as to block exhaust flow from the misfiring cylinder.
