What are the reasons for the Wuling Rongguang feeling sluggish and powerless when accelerating?

[McRyan]

The reasons for the Wuling Rongguang feeling sluggish and powerless when accelerating include: clogged three-way catalytic converter, degraded ignition performance of spark plugs, abnormal fuel injection, etc. Below are detailed cause analyses and solutions: Clogged three-way catalytic converter: Sluggish acceleration and a feeling of being stifled are likely caused by a clogged three-way catalytic converter. When clogged, it restricts engine exhaust flow, causing the engine's RPM increase to lag significantly behind the throttle pedal's depression depth, resulting in a stifled and powerless sensation. Solution: Clean the three-way catalytic converter by removing it, soaking it in oxalic acid or toilet cleaner to break down carbon deposits, and restore it to normal condition. Degraded ignition performance of spark plugs: As the direct component for igniting the air-fuel mixture, the spark plug's performance directly affects the engine's power output. During acceleration, if the spark plug's ignition performance degrades and fails to produce a high-intensity spark promptly, the suddenly increased fuel injection cannot combust fully, leading to sluggish and stifled acceleration. Solution: Use dry tissue or cloth to wipe the distributor inside and out, along with wires, then spray some desiccant specifically designed for the distributor cap, battery terminals, spark plugs, high-voltage wires, and ignition coil. Abnormal fuel injection: For gasoline to be injected into the cylinder in a well-atomized form, sufficient pressure is required as a foundation, with the injector nozzle serving as the passage. Therefore, when the nozzle is clogged, the injected fuel cannot form a good atomized state or reach sufficient injection volume, resulting in sluggish and stifled acceleration. Solution: Gently insert a sewing needle into the nozzle and stir back and forth to clean the injection holes, allowing it to be cleaned and reused.
