Solution

1. Preparation

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

2. Inspect and Replace Air Filter

• Remove the air intake duct to access the air filter.
• Check the air filter for dirt and damage; replace it if dirty or clogged.
• Reattach the air intake duct securely.

3. Fuel Pressure Check

• Locate the fuel pressure test port on the fuel rail.
• Connect a fuel pressure gauge to the test port.
• Start the engine and observe the pressure reading; compare it to manufacturer specifications.
• If pressure is low, inspect the fuel pump and fuel filter for issues; replace if necessary.

4. Ignition System Inspection

• Remove the engine cover (if applicable) to access the ignition coils and spark plugs.
• Check the spark plugs for wear (electrode condition, gap) and replace if necessary.
• Test ignition coils with a multimeter for proper resistance; replace any faulty coils.

5. Throttle Body Cleaning

• Disconnect the throttle body connector and remove the throttle body from the intake manifold.
• Clean the throttle body with throttle body cleaner and a soft brush to remove carbon buildup.
• Reinstall the throttle body and reconnect the electrical connector.

6. MAF Sensor Service

• Disconnect the MAF sensor connector and remove it from the air intake system.
• Clean the MAF sensor using MAF cleaner; avoid touching the sensor elements.
• Reinstall the MAF sensor and reconnect the electrical connector.
