Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, screwdriver, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct by loosening the clamps and disconnecting any sensors.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body.
Open the throttle plate manually to access the interior surface and clean thoroughly.
Reassemble the air intake duct and reconnect any sensors.

3. Inspect and Clean the Idle Air Control Valve

Locate the IAC valve, usually mounted on or near the throttle body.
Disconnect the electrical connector and remove the valve using a socket set.
Clean the valve using throttle body cleaner and a soft brush, ensuring no debris is left.
Reinstall the IAC valve and reconnect the electrical connector.

4. Test and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Disconnect the fuel lines using appropriate safety precautions.
Inspect the fuel filter for clogs; if needed, replace it with a new filter.
Reconnect the fuel lines securely and check for leaks.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals, ensuring they are tight.
Use the OBD-II scanner to clear any error codes and reset the ECU.
Start the engine and allow it to idle to check for proper operation.
