Why does the new car lack power when accelerating in first gear?

[VonMackenzie]

1. Pay attention to fuel pressure and lubricant quality when experiencing lack of power in first gear. Fuel pressure: To ensure normal engine starting, the residual fuel pressure in the fuel system after engine shutdown should not be lower than 2.5-3.5 kg/cm². Otherwise, insufficient pressure will prevent the fuel injector from spraying enough fuel for starting. If you repeatedly turn the ignition switch at this time, the fuel pressure will return to normal, making starting much easier. Lubricant quality: When winter comes, it's necessary to replace various lubricants in time, including engine oil, transmission oil, and power steering fluid. This is because ordinary lubricants become more viscous in winter, with poorer fluidity, leading to increased frictional resistance during component movement and making cold engine starting difficult. You can choose engine oil with slightly lower viscosity to reduce mechanical wear and protect the engine.
