Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during the repair process.
Allow the engine to cool completely before starting any work.

2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, socket set.
Remove the air intake duct connecting to the throttle body.
Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
Ensure the throttle plate moves freely and is not sticky.
Reinstall the air intake duct securely.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Tools Required: Socket set, torque wrench.
Remove the engine cover (if applicable) to access the spark plugs and ignition coils.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket set.
Remove the spark plugs using a spark plug socket.
Install new spark plugs, ensuring the gap is set to the manufacturer's specifications (typically around 0.028-0.032 inches).
Reinstall the ignition coils and reconnect the electrical connectors.

4. Fuel System Inspection

Tools Required: Fuel pressure gauge, fuel line disconnect tool.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure.
Compare the reading to the specifications in the service manual (typically around 50-60 psi).
If pressure is low, inspect the fuel filter and fuel pump for issues.
