FA20 Engine Problems and Reliability

1. Rough idling, shakes at low rpm. This is a problem with the firmware of the ECU. It can be fixed by upgrading or reloading the Engine Control Unit’s firmware.
2. The problem with a camshaft gear, which leads to a loss of oil pressure.
The engine requires high premium gasoline (98 octane number) and is exacting to a quality of the engine oil.
