Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, screwdrivers, multimeter, fuel pressure gauge, and replacement parts as needed.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean the Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the intake duct securely.

3. Check Spark Plugs and Ignition Coils

Remove the engine cover if necessary to access the ignition coils.
Disconnect the electrical connectors from the ignition coils and remove them using a socket.
Inspect the spark plugs for wear and replace if necessary (gap specifications: typically around 0.028-0.032 inches).
Reinstall the ignition coils and connectors.

4. Inspect the Fuel System

Connect a fuel pressure gauge to the fuel rail to check fuel pressure (specifications vary; consult service manual).
If pressure is low, check the fuel pump relay and fuses.
Replace the fuel filter if it appears clogged.

5. Check for Air Intake Leaks

Inspect the air intake hoses for cracks or loose connections.
Replace any damaged hoses or clamps.
Ensure the air filter is clean and replace if necessary.
