Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge.
Disconnect the battery to prevent electrical shorts and ensure safety.
Allow the engine to cool before starting any work.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use a throttle body cleaner and a clean cloth to remove carbon deposits from the throttle body.
Ensure the throttle plate moves freely and smoothly without obstruction.
Reconnect the air intake duct securely.

3. Replace Spark Plugs and Ignition Coils

Remove the ignition coil harness and unscrew the ignition coils from the cylinder head.
Replace old spark plugs with new ones, ensuring they are gapped correctly according to manufacturer specifications.
Install the new ignition coils and reconnect the harness.

4. Check Fuel System

Use a fuel pressure gauge to check if the fuel pressure is within the manufacturer's specifications.
If the pressure is low, replace the fuel filter and inspect the fuel pump for operation.
Ensure there are no leaks in the fuel lines and connections.

5. Inspect and Clean the MAF Sensor

Disconnect the MAF sensor connector and remove the sensor from the air intake tube.
Use MAF sensor cleaner to clean the sensor element gently.
Reinstall the MAF sensor and reconnect the connector.

6. Verify Electrical System

Use a multimeter to check battery voltage while the engine is running; it should be between 13.5 to 14.5 volts.
Inspect all fuses related to the engine management system for continuity and replace if necessary.
