Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down if it has been running.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body’s interior and the throttle plate.
Reinstall the air intake duct securely.

3. Inspect and Clean the Idle Air Control Valve (IACV)

Tools Required: Socket set, screwdriver, cleaning solvent
Locate the IACV (usually near the throttle body).
Disconnect the IACV connector and remove the valve from its mounting.
Clean the IACV with a suitable solvent and ensure the ports are free from carbon deposits.
Reinstall the IACV and reconnect the electrical connector.

4. Test and Replace Fuel Pump (if necessary)

Tools Required: Fuel pressure gauge, socket set, safety goggles
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) to check the fuel pressure; it should meet manufacturer specifications (typically around 40-50 psi).
If pressure is low, remove the fuel pump assembly from the fuel tank and replace it with a new fuel pump.
Reassemble everything securely.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes from the ECU.
Start the engine and allow it to idle, checking for any further issues.
