Check the engine ignition coil and spark plugs. Inspect the working performance of related sensors, such as the throttle position sensor, air flow meter, and intake manifold pressure sensor. Check the contamination level of the air filter. If it is clogged, it may cause a rich mixture condition, so clean or replace it if necessary. Check for any fuel injector leakage and the working performance of the fuel pressure regulator. Visit a professional 4S shop to inspect the related controllers.
