- The problem
- Fuel injection system reconfiguration to comply with engine emission standards cause higher engine vibration levels which lead to early wear and complete failure of the secondary throttle return mechanism.
- The risk
- In the event the primary throttle return fails, failure of the secondary throttle return system would not provide protection against loss of throttle control.
- The fix
- A new production secondary throttle return system configuration will be installed.
