Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool before starting work.

2. Inspect and Clean Air Intake System

Remove the air intake duct:
- Use a socket set to remove the clamps and disconnect the duct.
Inspect the air filter:
- Replace if dirty or clogged.
Clean the throttle body:
- Use throttle body cleaner and a soft cloth to remove carbon deposits.

3. Check and Replace Spark Plugs

Remove spark plug wires carefully:
- Use a spark plug socket and ratchet.
Inspect each spark plug for wear:
- Replace any that are worn or fouled.
Reinstall new spark plugs:
- Torque to manufacturer specifications (typically around 13-15 lb-ft).

4. Test and Adjust Fuel Pressure

Connect a fuel pressure gauge to the fuel rail:
- Follow the manufacturer's instructions for location.
Start the engine and check the pressure:
- Compare readings to manufacturer specifications.
If pressure is low, inspect the fuel pump and replace if necessary.

5. Inspect Exhaust System

Visually inspect exhaust pipes and catalytic converter:
- Look for signs of leaks or blockages.
If blockage is suspected, remove the catalytic converter and clean or replace it.
