What Are the Reasons for Engine Not Accelerating?

[MacParker]

Mainly caused by incorrect ignition timing, low fuel pressure, intake system air leakage, throttle position sensor or air flow meter malfunction, poor injector performance, or EGR system malfunction. Troubleshooting steps: 1. After starting the engine, check if the 'Check Engine' warning light turns off. 2. If the warning light does not turn off, inspect the cause and location of the fault based on the fault code. 3. Check if the ignition timing is excessively delayed. 4. Verify if the EGR system is functioning properly. 6. Inspect whether the intake and exhaust systems are blocked. 7. Check if the signals from the air flow meter, throttle position sensor, crankshaft position sensor, camshaft position sensor, and oxygen sensor are normal.
