Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before starting work.

2. Clean or Replace the Idle Air Control Valve (IAC)

Tools Required: Socket set, cleaning solvent, soft brush.
Remove the IAC valve from the throttle body by unscrewing the mounting bolts.
Clean the valve using a suitable cleaning solvent and a soft brush.
If cleaning does not resolve issues, replace the IAC with a new unit, ensuring it is properly seated and secured.

3. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth or brush.
Remove the intake duct to gain access to the throttle body.
Clean the throttle body with throttle body cleaner, ensuring the butterfly valve is free of carbon deposits.
Reinstall the intake duct securely.

4. Check Fuel System

Tools Required: Fuel pressure gauge, safety goggles.
Connect the fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure; it should match the manufacturer’s specifications.
If pressure is low, inspect the fuel pump, filter, and fuel lines for issues, replacing components as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes from the engine control module.
