What could be the reason for a sudden loss of power when pressing the accelerator in an Emgrand?

Driving and suddenly losing power when pressing the accelerator could be an issue with the fuel pump. Here is some relevant information: 1. Positioning of the Geely Emgrand: The Emgrand, with its brand proposition of 'Excellence, Stability, and Prestige,' represents Geely Automobile's development direction focusing on safety, energy efficiency, and environmental protection. 2. Logo of the Geely Emgrand: Its logo design is noble and exudes a strong international character, effectively shedding the historical baggage of Geely's original image while inheriting excellent inherent cultural genes. 3. Products of the Geely Emgrand: Following the Emgrand EC718 and EC718-RV, subsequent models include the GT, EC8, EX7, EX8, ET-9, EX9, and other sports cars, SUVs, MPVs, and pickup trucks, offering a rich and extensive product range.

I had a similar issue with my Emgrand before - pressing the accelerator on the highway with no response from the car, which was quite scary. Later I learned the main cause was likely severe carbon buildup in the throttle body jamming it, preventing air from entering the engine for combustion. Other possible causes include a faulty accelerator pedal sensor failing to send signals to the ECU, or loose wiring connections. A failed fuel pump cutting off supply or degraded transmission fluid causing slippage in the Emgrand's CVT are also common reasons for power loss. That time I got the throttle body cleaned and the problem was solved. Routine maintenance tips: Check the fuel filter every 20,000 km, replace aging spark plugs promptly to prevent recurrence. Safety advice: If sudden power loss occurs, immediately pull over safely with hazard lights on - don't force continued driving to avoid hazards. While the Emgrand drives smoothly, don't neglect minor maintenance - developing good habits saves trouble down the road.

My car repair experience tells me that sudden power loss in Emgrand is often caused by several common issues: a faulty throttle sensor sending inaccurate signals, causing the ECU to miss acceleration commands; a dirty throttle body with restricted opening, which can be fixed by removing and cleaning it; a clogged fuel filter leading to insufficient fuel supply, making the engine struggle; or aging ignition coils failing to spark the plugs, which can also trigger this phenomenon. Simple self-check: first, check if the dashboard warning light is on, then try gently pressing the accelerator a few times to see if power returns. Preventive measures: regularly change transmission fluid to prevent CVT slippage and keep the engine bay clean to reduce carbon buildup. In severe cases, have a professional shop use a diagnostic tool to check for error codes—avoid disassembling parts randomly. Regular maintenance should focus on electrical connections; early detection saves effort and money.

The power interruption issue in the Emgrand is quite worth discussing. Engine-related factors such as aging ignition coils causing misfires; intake manifold leaks leading to vacuum loss and disrupted air-fuel ratio; faulty sensors like the mass airflow meter sending incorrect signals. Worn fuel pumps may result in insufficient pressure and fuel supply issues, while transmission chain slippage can occur with prolonged use. If encountered on the road, don't panic - safety first, pull over. Routine maintenance includes cleaning the throttle body every six months and using genuine parts to replace sensors to avoid false signals. These methods are simple yet effective for maintaining your beloved car's performance.
