Why does the Wuling Rongguang have weak acceleration and cannot increase RPM?
3 Answers
Wuling Rongguang has weak acceleration and cannot increase RPM due to clutch oil leakage. The following is an introduction about Wuling Rongguang: 1. Features: "Size" is the most notable focus of Wuling Rongguang and also the intrinsic value of the product. 2. Exterior: The extended wheelbase of 2700mm adopts an ultra-long wheelbase design, effectively increasing the interior space while maintaining a harmonious body proportion for a comfortable driving experience. The extension of Rongguang is not simply about lengthening the body but involves upgrading the chassis technology to enhance the more critical indicator affecting space—wheelbase extension, ensuring a coordinated and safe proportion between the wheelbase and the lengthened body.
I know all too well about the Wuling Rongguang's lack of power when accelerating. Not long ago, my own car had the same issue. The engine seemed to be gasping for air, and no matter how hard I pressed the gas pedal, there was no response. Here's how we can troubleshoot: First, check if the air filter is clogged to the point of being blackened—insufficient air intake will make the engine weak. Next, inspect the spark plugs; poor ignition directly affects acceleration. Also, look at the fuel pump and fuel injectors—if fuel supply is inadequate, the RPMs definitely won't rise. Last time, I found that my fuel filter was severely clogged, cutting off fuel supply. Additionally, don’t overlook carbon buildup on the throttle body—if the carbon layer is too thick, the throttle opening can’t keep up, and the throttle response will lag. You can check all these yourself, but if nothing works, you’ll need to take it to a professional repair shop to read the fault codes with a computer.
Having repaired many Wuling Rongguang models, the common causes for lack of acceleration power are usually these issues: severely aged and eroded spark plugs with insufficient ignition capability, causing RPM to stall; clogged gasoline filters due to prolonged use, leading to poor fuel supply; faulty throttle pedal position sensors where signals fail to reach the ECU when pressed; and clutch slippage, which is more noticeable as the engine revs high but the vehicle speed doesn't increase. I recall one owner whose car idled fine but lost power upon acceleration—it turned out the catalytic converter was clogged, trapping exhaust gases and choking the intake. To prevent this, avoid using fuel from small gas stations and regularly clean carbon deposits.
