Check the working condition of the ignition module and spark plugs. If the condition is not good, it is recommended to replace the spark plugs. For excessively rich fuel correction, replace the air flow sensor. Check the fuel pressure and conduct an off-site road test with a fuel pressure gauge connected. If the fuel pressure is insufficient, replace the fuel pump and fuel filter. Check the engine control module and wiring. Disassemble the wiring harness connector, inspect the connector components for obvious issues, and the engine control module can be removed.
