The cool car can't add the throttle. What happened?

There are many reasons why the throttle can't be added, such as poor intake and exhaust and too much carbon deposition. There is something wrong with ignition, airflow or intake pressure signal, broken throttle sensor, wrong timing and phase, insufficient gasoline pump pressure, damaged crankcase ventilation valve, engine computer and other cars.
