Spray throttle body cleaner inside the throttle body and use a rag to wipe off any carbon buildup.
Reinstall the air intake duct and securely fasten all clamps.

3. Replace Fuel Filter

Tools Required: Fuel line disconnect tool, socket set, rags.
Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Use the fuel line disconnect tool to remove the old fuel filter.
Install the new fuel filter in the correct orientation.
Reconnect the fuel pump fuse and check for leaks.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench.
Remove the ignition coil covers to access the spark plugs.
Use a socket set to remove the old spark plugs and inspect them for wear or damage.
Install new spark plugs, ensuring they are gapped correctly. Use a torque wrench to tighten to manufacturer specifications.
Reinstall the ignition coil covers.

5. Test Fuel Pressure

Tools Required: Fuel pressure gauge.
Connect the fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure readings. Compare with manufacturer specifications.
If the pressure is low, consider replacing the fuel pump.
