Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
3. Reinstall the air intake duct securely.
Tools Required: Throttle body cleaner, soft brush, socket set.

3. Inspect and Replace the Accelerator Pedal Position Sensor (if faulty)

Sub-steps:
1. Locate the accelerator pedal position sensor on the accelerator pedal assembly.
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor mounting screws and take out the old sensor.
4. Install the new sensor and secure it with screws.
5. Reconnect the electrical connector.
Tools Required: Screwdriver set, socket set.

4. Check and Refill Transmission Fluid
