What are the reasons why the Excelle's speed does not increase when stepping on the accelerator?

The reasons why the Excelle's speed does not increase when stepping on the accelerator are: clogged fuel lines, clogged spark plugs, or carbon buildup in the throttle. Taking the 2020 Excelle as an example, it is a compact car with body dimensions of: length 4468mm, width 1765mm, height 1469mm, wheelbase 2611mm, fuel tank capacity 40l, and body weight 1070kg. The 2020 Excelle has a front suspension of MacPherson independent suspension and a rear suspension of compound torsion beam non-independent suspension, with a maximum horsepower of 107ps, maximum torque of 133nm, maximum power of 79kw, and is paired with a 5-speed manual transmission.
My Buick Excelle also experienced the issue of not accelerating when pressing the throttle before. This is usually a problem with the fuel system, such as an aging fuel pump not supplying enough fuel, or clogged fuel injectors preventing fuel from spraying, causing the engine to not receive sufficient fuel. Additionally, a dirty air filter can obstruct air intake, making the air-fuel mixture too lean. Ignition system failure is also a common cause, with too much carbon buildup on spark plugs or damaged ignition coils failing to spark. If transmission slippage occurs in an automatic transmission car, it could be due to worn torque converters or clutch plates failing to transmit power. A clogged catalytic converter can prevent exhaust gases from escaping, leaving the engine powerless. I must remind you not to press the throttle hard for extended periods, as it can easily damage the car. First, perform a simple check: see if the air filter is clean and try replacing the oil filter. If you can't fix it yourself, take it to a professional repair shop immediately to diagnose the ECU data stream and avoid more serious damage. Regular maintenance should include periodic cleaning of the fuel system to prevent such faults from recurring.
As a car enthusiast who often tinkers with vehicles, I've found that the delayed throttle response in the Excelle might be related to the electronic control system. Signal drift from the throttle position sensor can cause the ECU to issue incorrect commands, making it think you haven't pressed the pedal deeply enough. A faulty fuel pressure regulator can also lead to insufficient fuel supply. Don't overlook excessive ignition timing deviation or incorrect spark plug gap, which also affect acceleration. If you feel slippage during acceleration, it could be due to a clogged transmission valve body or worn clutch components. Exhaust manifold leaks causing backpressure issues result in power loss. I recommend using an OBD code reader to connect to the diagnostic port for convenient fault code checking. If it's a sensor issue, replacing the component solves the problem quickly and effortlessly. For daily prevention, regular oil changes to maintain cleanliness and reduce carbon buildup are crucial habits to develop.
When I was younger, I also experienced the issue of not being able to step deep on the accelerator and lacking power while driving a Buick Excelle. It was usually caused by poor fuel quality clogging the fuel filter or aging ignition coils resulting in insufficient spark. A faulty brake light switch accidentally activating the power limitation system is also common. The simplest checks are whether a fuse is blown, whether the tire pressure is sufficient, and whether the wheel transmission is smooth. Safety first—don't push it; pull over to check if the temperature gauge is normal. If the problem persists, seek a mechanic to avoid accidents on the highway. During maintenance, pay more attention to the battery voltage to ensure a stable power supply system.
