What's the reason for the Jinbei vehicle's sluggish acceleration and muffled performance when refueling?

This situation may occur due to damage to certain sensors around the engine, or damage to certain components around the engine. The most likely causes are a faulty throttle body or mass air flow sensor. Here is additional information: 1. Engine fuel system: The engine fuel system is a common problem area in vehicles. Clogged fuel injectors, leaking fuel lines, reduced fuel pump power, or a blocked fuel filter can all lead to poor vehicle performance. In addition to fuel, the engine also requires air. If components like the air filter or throttle body are clogged or malfunctioning, resulting in insufficient air intake, it can also cause sluggish acceleration and slow speed increase. 2. Crankshaft position sensor failure: This can cause the vehicle to lose the timing of ignition and fuel injection, putting the vehicle into a limp mode with poor acceleration. Replacing the sensor can fix the issue. A damaged fuel pump or fuel pump pressure leakage, leading to insufficient fuel pressure and inadequate fuel supply, will naturally result in poor acceleration. Replacing the fuel pump can resolve this. A clogged fuel pump filter can also cause insufficient fuel pressure, and replacing the filter can fix the problem.
This Jinbei vehicle is struggling to accelerate and feels sluggish when refueling, which sounds like a clogged exhaust system or restricted air intake. I've encountered a similar situation before, and it turned out to be a completely blocked catalytic converter. The exhaust couldn't escape, making the car feel sluggish and lacking power during acceleration. You should first check if the air filter is dirty. If there's too much dust, air can't get in, and the engine will naturally lack air, causing it to feel sluggish. The fuel system also needs inspection—for example, a clogged fuel pump or fuel line can lead to incomplete combustion. I recommend stopping the vehicle and either cleaning the filter or replacing it. If the issue persists, don't push it—take it to a repair shop for professional diagnostics with specialized equipment. Preventive maintenance is crucial; regularly checking these components can help avoid major problems.
I've experienced this issue with a Jinbei van before. When accelerating, the car feels sluggish and lacks power, which is usually caused by a decline in engine performance. It could be due to worn-out spark plugs, resulting in poor ignition efficiency and incomplete combustion, leading to insufficient power. Alternatively, the fuel injectors might be clogged, preventing proper fuel spray and making the car feel sluggish and unable to accelerate. I recommend using a multimeter to check if the electrical circuit is functioning properly, and then inspect the fuel supply lines for any leaks. If the issue lies with the catalytic converter, it's best to replace it promptly. Ignoring such faults could potentially damage the engine internals. Keep an eye on fuel consumption while driving—if it suddenly increases, be alert. When getting repairs, choose a reliable shop to avoid secondary issues.
