What's the reason for no acceleration when pressing the gas pedal?
2 Answers
Reasons for no acceleration when pressing the gas pedal: 1. Fuel line blockage; 2. Dirty fuel filter; 3. Abnormal high-voltage spark plugs; 4. Air leakage in the cylinder or carbon deposits causing improper valve closure. Solutions for no acceleration when pressing the gas pedal: 1. Clean the fuel line; 2. Replace the fuel filter; 3. Replace the spark plugs; 4. Remove carbon deposits. Precautions when pressing the gas pedal: 1. Press and release the gas pedal gently and slowly; 2. Coordinate the clutch release with the gas pedal press for smooth operation; 3. Select appropriate gears to keep the engine running at medium speed and larger throttle most of the time to save fuel; 4. Before stopping or turning off the engine, release the gas pedal first and avoid revving the engine abruptly.
Last time my car had the same issue, the RPM surged when I floored the gas pedal but the speed wouldn't increase. Turned out the clutch plates were completely worn out—a common problem with manual transmissions. For automatic transmissions, it might be due to deteriorated transmission fluid causing power transfer slippage. Clogged fuel lines can also lead to this, like dirty fuel injectors or an aging fuel pump resulting in insufficient fuel supply and weak acceleration. Low tire pressure increases rolling resistance too, making acceleration feel sluggish. Don't delay with such problems—get to a repair shop immediately to read the trouble codes. Check the drivetrain first before investigating the engine, otherwise you risk getting stranded with a breakdown.
