Why does the Wuling Rongguang lose power while driving?
4 Answers
If the Wuling Rongguang loses power while driving, the fuel system should be checked, especially the fuel pump. It could be due to poor-quality fuel or a dirty fuel tank. Here is some information about the Wuling Rongguang: 1. Dimensions: The Wuling Rongguang measures 4 meters in length, 1620mm in width, and 1915mm in height. Compared to traditional microvans (under 3.8 meters), it is larger in all dimensions, providing more space for passengers and cargo. 2. Features: The most notable feature of the Wuling Rongguang is its size, which is also the core value of the product. Unlike traditional microvans that are simply elongated, the Wuling Rongguang's "largeness" is comprehensive and well-deserved. 3. Powertrain: The Wuling Rongguang is equipped with a new-generation small-displacement (1.2L) high-power B-series engine, boasting an outstanding power-to-displacement ratio of 52.2KW/L.
I've been driving my Wuling for almost ten years and have encountered the issue of not being able to accelerate several times, mostly due to fuel system problems. It could be a faulty fuel pump or a clogged fuel filter, which cuts off the gasoline supply, making the engine naturally weak in acceleration. When the fuel pump fails, the humming sound from under the car will weaken—you can listen for it while driving. A dirty throttle body might also obstruct air intake, causing sluggish acceleration. I suggest first checking if the fuel tank cap is tightly screwed on to avoid air leaks. Regular maintenance, like replacing the fuel filter, can prevent many issues. If this happens on the highway, slow down immediately, pull over safely, turn on the hazard lights, and wait for assistance—safety first. Proper maintenance for older cars ensures reliability, otherwise breakdowns on the road can be really frustrating.
As a Wuling Rongguang owner myself, acceleration issues are often related to sensors. For example, a faulty throttle position sensor can cause the ECU to miscalculate fuel injection, resulting in acceleration hesitation. A severely clogged air filter restricting airflow can also slow down the vehicle. You could try connecting a mobile OBD scanner to the diagnostic port to check trouble codes and identify the root cause. Additionally, severely clogged fuel injectors in the fuel system can prevent proper gasoline spraying, leading to poor acceleration. Don't always wait until the fuel gauge hits empty before refueling - top up when it reaches one-quarter. Regular cleaning of injectors and throttle body, plus paying attention to dashboard warning lights, can save you from costly major repairs.
This issue commonly occurs with fuel pump failures or ignition system malfunctions. When the fuel pump wears out, pressure drops and gasoline can't reach the engine, causing jerky acceleration. The check method is simple - listen for the normal working hum of the fuel pump when starting the car. If ignition coils or spark plugs are aging, the spark becomes intermittent, leading to inconsistent power. It's best to try replacing spark plugs, which generally should be changed every 30,000 kilometers. Also check battery voltage, as low voltage can affect fuel delivery. Simple pre-drive maintenance can easily prevent roadside embarrassments.
