Solution

1. Preparation

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

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, rag, socket set
Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use a throttle body cleaner to spray the inside of the throttle body.
3. Wipe clean with a rag to remove carbon build-up.
4. Reattach the air intake duct securely.

3. Check and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the ignition coils by unscrewing them from the cylinder head.
2. Take out the old spark plugs using a spark plug socket.
3. Inspect the old spark plugs for wear and replace them with new ones, ensuring they are gapped correctly.
4. Reinstall the ignition coils and torque them to the manufacturer’s specifications.

4. Test the Fuel System

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "On" position (without starting the engine) to check the fuel pressure.
3. Compare the reading to the manufacturer’s specifications; replace the fuel pump if pressure is low.
4. If necessary, replace the fuel filter as part of the maintenance.
