Nissan Grand Livina Fuel Injector Malaysia
HR16DE uses port injection — fuel injectors spray before the intake valve, so carbon buildup on injectors is minimal. Injectors rarely need cleaning or replacement before 150,000 km on RON95 or RON97. Symptoms of failing injector: rough idle, P030X misfire codes, one cylinder running lean. Injector cleaning service is a precautionary measure at 80,000 km on older units. Use top-tier RON97 if possible to keep injectors clean.

- Misfire codes P0301–P0304: diagnose individual injector before replacing all
- OEM Denso or Bosch injectors for replacement — avoid cheap unbranded units
- RON97 fuel reduces injector deposits in direct injection engines
