 When a catalyst-damaging misfire occurs (MIL blinking), the following fail-safe operation is performed for catalyst overheat malfunction prevention.
  1. Under a low load and at a low engine speed:

    - Fuel cut is performed on the malfunctioning cylinder.

  2. Under a high load and at a high engine speed:

    - Throttle valve opening angle control is performed.

    - Fuel cut is performed on all cylinders or the malfunctioning cylinder.
