P2187, Bank 1, system too lean (idle), possible causes:
- Fuel injectors are clogged or stuck.
- Air leak in the intake system after the mass airflow sensor.
- Leak in the exhaust system.
- The mass airflow sensor (G70) is giving incorrect readings.
- The fuel pump is not providing enough pressure.
- Malfunction in the fuel vapor system (check component N80).
