What is the reason why Wuling Zhiguang cannot accelerate when the engine is hot?

Check the fuel pressure. Check whether the intake manifold (including the air filter) is unobstructed. The following is a related introduction to Wuling Motors: 1. Introduction: Wuling is the registered trademark and brand of Liuzhou Wuling Automobile Co., Ltd. This logo has been fully authorized for use by SAIC-GM-Wuling. 2. Appearance: Wuling Hongguang adopts the currently very popular double U front face design and a three-dimensional vertical waterfall-style chrome-plated air intake 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 eye-catching eagle-eye crystal diamond headlights and feather-shaped crystal diamond front fog lights further enhance the vehicle's sense of grade. The two powerful lines on the engine hood give a strong sense of power visually.

I've experienced the issue of the Wuling Zhiguang not accelerating when the engine is hot several times. Possible reasons include the fuel pump failing under high temperatures, as heat increases wear and makes the pump less flexible. Or the ignition coil overheating causing no spark, and spark plugs may not fire properly under high heat after prolonged use. Sometimes the air filter is clogged, restricting airflow and starving the engine. Additionally, if sensors like the oxygen sensor are dirty or faulty, the ECU can't control the fuel mixture properly, leading to poor acceleration. Regular maintenance can prevent this, such as cleaning the fuel system or replacing filters. Hot engine failures are dangerous, especially on highways - sudden loss of power could cause serious accidents. My previous car had to be towed to the shop, where they found and replaced a faulty fuel pump. Always monitor engine temperature to prevent prolonged overheating.

As a mechanic with years of experience, I think the common issues causing the Wuling Zhiguang to lose power when hot are a few key points. First, check the fuel system: a clogged fuel filter can prevent fuel from entering, and the fuel pump's performance may degrade when the engine is hot. Inspect the ignition system—old spark plugs or failing ignition coils under high heat can cause misfires. Also, look at the air supply: a dirty air filter or carbon buildup in the throttle body can be culprits. Faulty sensors, like the temperature sensor, can also affect performance. A simple self-check method: try accelerating when the engine is cold and observe the response. If the problem only occurs when the engine is hot, prioritize checking the fuel pump and ignition coils. Avoid tampering with the electrical system to prevent bigger issues. I recommend warming up the engine for a few minutes before driving, but if the problem persists when the engine is hot, don't push it—take it to a professional shop for a full inspection. I've seen car owners try to save money by delaying repairs, only to end up stranded and spending more in the end.

My Wuling minivan also had this issue before—it wouldn't accelerate when hot, which was really annoying. It's likely an ignition system or fuel pump problem: old spark plugs failing to ignite at high temperatures, or a heat-damaged fuel pump causing insufficient fuel supply. Faulty sensors like the air-fuel ratio sensor could also be the culprit. Replacing the spark plugs during maintenance fixed it. Regular maintenance is key—avoid long trips in hot weather. This issue affects safety as failed acceleration can be terrifying. Fix it early for peace of mind.

When using Wuling Zhiguang to pick up and drop off children at home, you may encounter the issue of insufficient power when refueling a hot car. Possible causes include the fuel pump failing under high temperatures or clogged fuel injectors causing fuel line blockages; overheating ignition coils leading to delayed ignition. Sensor malfunctions can cause the computer to improperly control fuel supply. This is particularly dangerous, especially when driving in rain or at night, as it increases the risk of accidents. It is recommended to check the temperature gauge before driving and to stop by the roadside and call for assistance if a hot car malfunction occurs. Regular maintenance, such as cleaning the fuel system and replacing the air filter, can prevent such issues. My driving habit is to let the car warm up for a short while after a cold start for short trips, reducing the stress on the hot engine.
