Does the Wuling Hongguang have issues with idle vibration and acceleration?
3 Answers
Wuling Hongguang has no issues with idle vibration and acceleration. Below is relevant information about the Wuling Hongguang: 1. Introduction: The Wuling Hongguang is the first independently developed crossover product between commercial vehicles and passenger cars launched by SAIC-GM-Wuling. This product features a smooth exterior design, along with a diverse and practical spacious driving space. 2. Exterior: The exterior combines a grand appearance with popular elements. The Wuling Hongguang adopts the currently very popular double-U front face design and a three-dimensional vertical waterfall-style chrome-plated grille, which not only makes the front of the car look more fashionable and dynamic but also inherits some characteristics of the General Motors series. The striking eagle-eye crystal diamond headlights and feather-shaped crystal diamond front fog lights further enhance the vehicle's sense of grade. Two powerful lines bulge on the engine hood, giving a strong visual sense of power.
My Wuling Hongguang has been running for over three years, and recently I also encountered severe idling vibrations and sluggish acceleration when stepping on the throttle. The most common causes for such issues are excessive engine carbon buildup clogging the throttle body or aging spark plugs with weak ignition. Since this Wuling is often used for hauling goods and driven on poor road conditions, it's more prone to carbon deposits. I also noticed that if the engine mounts are worn out, just like faulty shock absorbers, the vibrations can directly transfer into the cabin. Additionally, insufficient fuel pump pressure or a dirty air filter can affect fuel supply and air intake. I recommend starting with a throttle body and fuel injector cleaning, which can be done for a few dozen bucks, then checking the spark plugs' lifespan. For manual transmission models, worn clutch plates can also cause weak acceleration—these are all key areas to inspect.
My friend just got his Wuling Hongguang fixed, with exactly the same symptoms you described—idling so rough the steering wheel vibrates like a massage chair, and flooring the gas pedal during overtaking but the speed barely climbs. The mechanic immediately pulled the spark plugs for inspection, and sure enough, two cylinders had burnt-out electrodes, causing misfire-induced shaking. Replacing with new spark plugs cost just over a hundred bucks including labor. Other common culprits are leaking ignition coils or fuel injectors clogged by residue from low-quality gasoline, leading to overly lean air-fuel mixture. Prioritize checking these three areas—don’t rush into part replacements; reading trouble codes first can save you unnecessary expenses. Wuling parts are affordable, but skip roadside stalls; opt for certified repair shops for more reliable diagnostics.
