1. Locate the air filter housing and remove the screws or clips.
2. Take out the air filter and inspect it for dirt and debris.
3. If dirty, clean it with compressed air or replace it with a new one.
Tools Required: Screwdriver, compressed air (if cleaning).

3. Test Fuel Pressure

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Start the engine and observe the pressure reading; it should match the manufacturer's specification.
3. If pressure is low, check the fuel pump and fuel filter for issues.
Tools Required: Fuel pressure gauge.

4. Clean Throttle Body

Sub-steps:
1. Disconnect the throttle body electrical connector and intake duct.
2. Remove the throttle body from the intake manifold.
3. Clean the throttle body with throttle body cleaner and a soft cloth.
