The most common causes of Diagnostic Trouble Code P2118 are failure of the
throttle actuator control motor, a
failed pedal
position sensor, a faulty
throttle position sensor, an open or short in the actuator circuit, or a poor electrical connection anywhere in the control circuits for the foregoing components.
This problem may be caused by a coolant temperature sensor, idle air control valve,
throttle position sensor, or O2 sensor that may be
failing.
This may be related to a faulty

This sounds like the
throttle position sensor is
failing.
The lack of response to the accelerator pedal has quite a few potential causes that would have to be sorted out in a diagnostic including, just as a few examples, plugged fuel injectors, faulty oxygen sensors, fuel pump and / or filter, vacuum leaks including that caused by a faulty EGR system, ignition system malfunctions, bad valve timing if the timing belt or chain is worn or skipped, blocked exhaust (e.g., catalytic converter
fails or becomes clogged), a faulty airflow sensor or
throttle position sensor, and so forth.
If it is really dirty on the inside, if the idle control valve is
failing, or of the
throttle position sensor is
failing then this will occur...
