Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid electrical shock.

2. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Reassemble the air intake duct securely.

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

Disconnect the wiring harness from the accelerator pedal position sensor.
Remove the sensor from the accelerator assembly using a socket set.
Install the new accelerator pedal position sensor, making sure it clicks into place.
Reconnect the wiring harness.

4. Clean or Replace Mass Air Flow (MAF) Sensor (if necessary)

Disconnect the MAF sensor connector.
Remove the sensor from the air intake duct carefully.
Use MAF cleaner to spray the sensor elements; avoid touching them with fingers.
Reinstall the MAF sensor and reconnect the connector.

5. Inspect Fuel System

Check the fuel pressure using a fuel pressure gauge.
Replace fuel filter if pressure is below manufacturer specifications.
Inspect fuel injectors for proper operation; clean or replace if needed.
