Solution

1. Preparation

• Gather necessary tools and parts.

2. Address Faulty Components

A. Replace Spark Plugs

1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors.
3. Unbolt and remove the ignition coils.
4. Use a spark plug socket to remove the old spark plugs.
5. Install new spark plugs, ensuring the correct torque (typically 22 Nm).
6. Reinstall the ignition coils and reconnect the connectors.

B. Inspect and Clean Fuel Injectors

1. Remove the fuel rail if necessary, ensuring the fuel system is depressurized.
2. Remove the fuel injectors from the rail.
3. Clean the injectors using a dedicated injector cleaning solution or replace if damaged.
4. Reinstall the injectors and fuel rail, ensuring proper sealing.

C. Check Air Intake System

1. Visually inspect air intake hoses for cracks or loose connections.
2. Clean the Mass Air Flow (MAF) sensor if present, using MAF cleaner.
3. Reconnect all hoses and ensure a tight fit.

3. Reconnect Battery

• Reconnect the battery terminals, ensuring the positive terminal is connected first.

4. Clear Error Codes

• Use an OBD-II scanner to clear any stored error codes after repairs are completed.
