What's the matter with stepping on the gas pedal but the car not moving?

[MacElena]

Detailed explanations about the car not moving when stepping on the gas pedal are as follows: 1. Intake system problem. The air filter among the three filters needs frequent cleaning and replacement. If the air filter is clogged or the throttle system is blocked, the air intake will decrease, combustion will be insufficient, and power will drop. 2. Fuel system problem. After long-term use, carbon deposits may form on the fuel injectors, leading to clogging. This reduces fuel intake and causes insufficient atomization, naturally decreasing combustion efficiency and making the vehicle feel powerless. 3. Ignition system problem. If the car doesn't move when stepping on the gas and emits black smoke, it might be an ignition system issue. Carbon deposits on the spark plugs can cause poor ignition, resulting in decreased power and persistently high fuel consumption.
