Solution

1. Preparation

Gather required tools and parts.
Disconnect the battery to ensure safety during the repair.

2. Inspect and Clean Throttle Body

Tools Required: Torque wrench, socket set, throttle body cleaner, rags.
Remove the air intake duct connected to the throttle body.
Unbolt the throttle body using the socket set.
Clean the throttle body with throttle body cleaner and a rag, ensuring all carbon buildup is removed.
Reinstall the throttle body and secure it with the specified torque settings (check service manual for exact values).

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Remove ignition coils by unbolting and disconnecting the electrical connectors.
Remove the old spark plugs with a spark plug socket.
Install new spark plugs, ensuring they are gapped correctly according to specifications.
Reinstall ignition coils and secure with the torque specified in the service manual.

4. Test Fuel Pump and Replace if Necessary

Tools Required: Fuel pressure gauge, socket set.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the 'on' position (without starting the engine) to check fuel pressure.
If pressure is below specification, disconnect the battery and replace the fuel pump as per the manufacturer's guidelines.
