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.
