Solution

1. Preparation

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

2. Inspect and Clean Components

Air Filter and Intake System
- Remove the air intake duct.
- Inspect the air filter for dirt and debris. Replace if necessary.
- Clean the throttle body using throttle body cleaner and a soft cloth.
Fuel System
- Check the fuel filter for clogs and replace if necessary.
- Inspect fuel injectors for proper operation and clean if needed.

3. Test and Replace Ignition Components

Spark Plugs and Ignition Coils
- Remove spark plugs using a socket set. Inspect for wear or damage; replace if necessary.
- Test ignition coils with a multimeter. Replace any faulty coils.

4. Check and Replace Sensors

Throttle Position Sensor (TPS) and Mass Airflow Sensor (MAF)
- Disconnect the TPS and MAF connectors.
- Clean the MAF with MAF cleaner. Replace if defective.
- Test TPS with a multimeter. If it’s out of specification, replace it.

5. Reassemble and Reconnect

Reinstall all components in reverse order of removal.
