What causes insufficient power when the Wuling Rongguang's accelerator is fully pressed?

[JaylaDella]

Insufficient fuel pressure in the engine's fuel system, poor performance of the ignition system, or a clogged three-way catalytic converter can all lead to insufficient power when the Wuling Rongguang's accelerator is fully pressed. Low fuel system pressure or insufficient fuel supply: Common causes include a clogged fuel filter, excessive wear of the fuel pump, clogged or leaking fuel injectors, or a faulty fuel pressure regulator. These issues can result in abnormal fuel supply, leading to insufficient combustible mixture entering the engine and thus reduced power. It is necessary to check whether the fuel system is functioning properly and perform maintenance. Poor ignition system performance: Components such as the ignition coil and spark plugs in the ignition system are wear-prone parts and typically need replacement every 50,000 to 80,000 kilometers. If not replaced for a long time, insufficient ignition energy can prevent the complete combustion of the combustible mixture in the cylinders, leading to significantly reduced power. The performance of ignition system components should be checked and replaced if necessary. Clogged three-way catalytic converter: Once the three-way catalytic converter is clogged, the oxygen sensor cannot function properly, greatly affecting the accuracy of the oxygen sensor signals received by the engine. This directly results in inaccurate control of fuel injection, air intake, and ignition, causing power loss and weak acceleration. Typically, when the three-way catalytic converter is clogged, the engine's fault light will illuminate, alerting the owner to check promptly. The three-way catalytic converter should be cleaned or replaced.
