Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, throttle body cleaner, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean the Throttle Body

Disconnect the negative battery terminal to prevent electrical issues.
Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reattach the air intake duct securely.

3. Check and Replace the Fuel Filter (if necessary)

Locate the fuel filter, typically along the fuel line.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter, taking care to catch any spills.
Remove the old filter and install the new one, ensuring proper orientation.
Reconnect the fuel lines and reinstall the fuel pump fuse.

4. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coil or spark plug wire from each spark plug.
Use a spark plug socket and ratchet to remove the old spark plugs.
Inspect the old plugs for wear or deposits. Replace with new plugs if necessary, ensuring the gap is set to manufacturer specifications.
Reinstall the ignition coils or spark plug wires.

5. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position (without starting the engine) and check the pressure reading.
Compare the reading to manufacturer specifications; if low, further investigate the fuel pump or pressure regulator.
