Solution

1. Preparation

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

2. Address Air Intake Issues

Remove the air filter:
- Use a socket set to unfasten the air intake duct.
- Inspect the air filter; replace if dirty or clogged.
Clean the throttle body:
- Remove the throttle body using a socket set.
- Use throttle body cleaner and a soft cloth to clean the interior surfaces.
- Reinstall the throttle body and securely fasten it.

3. Fuel System Check

Check fuel pressure:
- Attach a fuel pressure gauge to the fuel rail.
- Start the engine and observe the pressure reading; it should match manufacturer specifications.
- If pressure is low, replace the fuel pump or filter as necessary.

4. Inspect Ignition System

Check spark plugs and coils:
- Remove the spark plugs using a spark plug socket.
- Inspect for wear or damage; replace if worn.
- Test ignition coils using a multimeter to ensure they are within specifications; replace faulty coils.

5. Exhaust System Inspection

Check for exhaust restrictions:
- Inspect the exhaust system visually for any damage or blockages.
- Use a pressure gauge to test back pressure; if it exceeds manufacturer specifications, replace the catalytic converter.
