Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, and clean rags.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto the throttle plate and use a soft brush to remove carbon deposits.
Wipe clean with a rag and ensure no cleaner residue is left.
Reinstall the air intake duct securely.

3. Inspect and Replace the Accelerator Pedal Position Sensor

Tools Required: Socket set, multimeter.
Locate the accelerator pedal position sensor under the dashboard.
Disconnect the electrical connector from the sensor.
Use a multimeter to check the sensor's resistance at various pedal positions.
If the readings are outside the manufacturer's specifications, remove the sensor using a socket set.
Install the new accelerator pedal position sensor and reconnect the electrical connector.
