Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting work.

2. Inspect and Clean Air Intake

Remove the air intake duct and inspect the air filter for dirt and obstructions.
Clean or replace the air filter as necessary.
Reattach the air intake duct securely.

3. Fuel System Inspection

Disconnect the fuel pump relay and relieve fuel pressure by starting the engine until it stalls.
Connect a fuel pressure gauge to the fuel rail and start the vehicle.
If pressure is below specifications, replace the fuel filter or fuel pump as necessary.

4. Ignition System Maintenance

Remove spark plugs and inspect for signs of wear, such as excessive carbon buildup or electrode wear.
Replace spark plugs if they appear damaged or worn.
Check ignition coils for proper functionality using a multimeter; replace any faulty coils.

5. Exhaust System Check

Inspect the exhaust system, focusing on the catalytic converter for any signs of blockage or damage.
If a blockage is found, consider replacing the catalytic converter.
