Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Clean Air Intake System

Tools Required: Screwdriver set, clean rags, throttle body cleaner.
Remove the air intake duct and visually inspect for blockages.
Clean the throttle body using throttle body cleaner and a clean rag.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter (if necessary)

Tools Required: Socket set, fuel line disconnect tool.
Locate the fuel filter; it may be integrated with the fuel pump.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines and remove the old fuel filter.
Install the new fuel filter, ensuring all connections are secure.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug gap gauge.
Remove the ignition coil(s) by unscrewing them from the cylinder head.
Remove the spark plugs using a spark plug socket and inspect for wear or deposits.
Replace with new spark plugs, ensuring the gap is set to manufacturer specifications.
Reinstall ignition coils and secure them.

5. Test Fuel System Pressure

Tools Required: Fuel pressure gauge.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading against manufacturer specifications.
If the pressure is low, check for fuel pump issues or clogs in the fuel lines.
