Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting work.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while manually opening the throttle plate.
Use a clean, soft cloth to wipe away any carbon buildup gently.
Allow the throttle body to dry completely before reassembling.

3. Check and Adjust Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor (usually mounted on the pedal assembly).
Inspect the sensor for proper mounting and alignment.
If misaligned, adjust the sensor to ensure correct positioning.
Reconnect any electrical connectors and secure them.

4. Upgrade Components (Optional)

Consider installing a performance throttle body for enhanced airflow.
Replace the engine air filter with a high-flow filter to improve air intake.
Upgrade the ECU with a performance tuning chip or reflash for better throttle mapping.

5. Reconnect and Test

Reconnect the air intake duct and ensure all clamps are secure.
Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
