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.
