Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner to spray the inside of the throttle body.
Wipe the throttle body with a soft cloth to remove carbon build-up.
Reattach the air intake duct securely.

3. Inspect and Replace Spark Plugs (if necessary)

Tools Required: Socket set, torque wrench
Remove the ignition coils by unscrewing them from the cylinder head.
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear or damage; replace if necessary.
Install new spark plugs, ensuring they are gapped correctly.
Reinstall the ignition coils and secure them with the appropriate torque.

4. Fuel System Inspection

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to “ON” without starting the engine and check the fuel pressure.
Compare the reading to manufacturer specifications; replace the fuel pump if pressure is low.

5. Electrical System Check

Tools Required: Multimeter
Test the battery voltage and alternator output while the engine is running.
Ensure the battery voltage is above 12.4 volts and the alternator is charging properly.
Replace the battery or alternator if any readings are below specifications.
