• Disconnect the battery before working on electrical systems.

2. Inspect and Clean Fuel Injectors

• Tools Required: Fuel injector cleaning kit, safety goggles, gloves.
• Remove the engine cover if necessary.
• Disconnect the fuel rail and remove the injectors.
• Use a fuel injector cleaning kit to clean each injector.
• Reinstall the cleaned injectors securely to the fuel rail.

3. Replace Air Filter

• Tools Required: Screwdriver or ratchet set (if necessary).
• Locate the air filter housing.
• Open the housing and remove the old air filter.
• Install a new air filter, ensuring it fits snugly.
• Close the housing securely.

4. Test Fuel Pressure

• Tools Required: Fuel pressure gauge.
• Locate the fuel pressure test port on the fuel rail.
• Attach the fuel pressure gauge and turn the ignition to the 'ON' position without starting the engine.
• Check the pressure reading against the manufacturer specifications.
• If the pressure is low, inspect the fuel pump and fuel filter for issues.

5. Replace Spark Plugs

• Tools Required: Socket set, torque wrench, anti-seize compound.

6. Inspect for Vacuum Leaks

• Tools Required: Smoke machine or carburetor cleaner.
