What are the faults causing poor engine acceleration?

[VonCharlotte]

Faults causing poor engine acceleration include: 1. Incorrect ignition timing; 2. Low fuel pressure; 3. Air leaks in the intake system; 4. Malfunction of the throttle position sensor or air flow meter; 5. Poor injector performance; 6. Abnormal operation of the exhaust gas recirculation system; 7. Weak ignition signal. When experiencing poor engine acceleration, the following inspections can be performed: 1. Check if the air filter is clogged and clean or replace it promptly; 2. Inspect the throttle position sensor; 3. Check for air leaks in the intake system; 4. Perform fault self-diagnosis to check for any fault codes.
