Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before beginning work.

2. Fuel System Inspection

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine to check for proper fuel pressure.
- Compare readings to manufacturer specifications.
Replace Fuel Filter (if clogged):
- Locate the fuel filter and relieve fuel system pressure.
- Disconnect fuel lines from the filter using a line disconnect tool.
- Remove the old filter and install the new one, ensuring correct orientation.
- Reconnect fuel lines and check for leaks.

3. Ignition System Maintenance

Inspect and Replace Spark Plugs:
- Remove the ignition coils by unscrewing them.
- Take out the spark plugs using a spark plug socket.
- Inspect for wear and carbon buildup; replace if necessary with OEM parts.
- Reinstall spark plugs and ignition coils, ensuring proper torque specifications.

4. Air Intake System Cleaning

Inspect and Clean:
- Remove the air intake duct to access the throttle body.
- Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon buildup.
- Reassemble the air intake duct securely.

5. Electrical System Check

Inspect Wiring and Connectors:
- Visually inspect all wiring harnesses and connectors leading to the ECU and sensors.
- Clean any corroded connectors and repair any frayed wires.
