Check if the car's air filter is clogged and clean it thoroughly if necessary. When the accelerator pedal is fully depressed, the throttle should open completely. Otherwise, adjust its cable or perform a pedal position sensor relearn. Inspect the car's high-voltage wires, spark plugs, and high-voltage sparks to see if they are too weak. When disconnecting the high-voltage wire connector, do so gently and avoid shaking it forcefully. Measure the fuel pressure to see if it is too low. If necessary, check the electric fuel pump, fuel pressure regulator, and fuel filter.

Last night while driving, I encountered an engine power loss warning. I've experienced this a few times before, which is usually related to fuel system blockage or sensor failure. First, ensure safety - don't panic, gradually reduce speed and pull over to the roadside, then turn on the hazard lights. Check if the engine oil level and coolant are sufficient to rule out simple issues. If the engine oil is dirty or the fuel filter is aging, they should be replaced promptly. Warning lights on the dashboard indicate the computer has detected an abnormality - it's best not to force drive to the repair shop for diagnostic scanning. Delaying too long may lead to more serious damage. I recommend going to a professional repair shop as soon as possible to check the mass airflow sensor or ignition coil issues. Regular maintenance can help reduce such unexpected occurrences.
