What causes the inability to accelerate the throttle right after starting the car?

[VanKendra]

Here are the reasons why the throttle cannot be accelerated right after starting the car: 1. Incorrect valve timing, such as poor sealing of intake and exhaust valves. 2. Poor performance, short circuit, or burnout of the fuel pump due to internal or wiring issues, leading to insufficient or stopped fuel supply. 3. Blockage in the intake system, such as the air filter or air flow meter, preventing proper combustion with fuel. 4. Internal engine faults, improper maintenance, premature or abnormal wear, cylinder pressure issues, or other potential problems. 5. Blockage in the fuel system, such as the injector, fuel filter, or poor fuel quality. 6. Abnormal spark plug ignition, aging components, exceeding normal lifespan, carbon deposits, or incorrect model selection (e.g., heat value). 7. Poor performance of the ignition system, such as spark plugs or high-voltage wires.
