Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Clean the Throttle Body

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.
Reinstall the air intake duct securely.

3. Check and Replace the Air Filter

Open the air filter housing and remove the old air filter.
Inspect the housing for debris and clean if necessary.
Install a new air filter, ensuring it fits snugly.

4. Address Vacuum Leaks

Visually inspect all vacuum hoses for signs of wear or damage.
Replace any damaged hoses with OEM or equivalent parts.
Ensure all connections are tight and secure.

5. Check and Clean the Idle Air Control Valve (IAC)

Locate the IAC valve, typically mounted on or near the throttle body.
Remove the IAC valve from its mounting.
Clean the valve with throttle body cleaner and a soft brush.
Reinstall the IAC valve and ensure it is properly secured.

6. Test Fuel Pressure

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.
If the pressure is below specifications, inspect the fuel pump and filter for issues.
